QGIS will not install on Ubuntu 22.04

Steps to reproduce the issue

sudo apt remove qgis sudo apt autoremove sudo apt remove geos

sudo apt install qgis

Versions

This has been true since Jammy was released. 3.22.4+ and 3.24.x all fail for the same reason.

Supported QGIS version

• [X] I'm running a supported QGIS version according to the roadmap.

New profile

• [ ] I tried with a new QGIS profile

Additional context

Whenever I upgrade to a new Ubuntu release, the release manager helpfully uninstalls my working version of QGIS, which I then have to reinstall. The reinstall is not working this time.

not reproducable - there's no libgdal.so.30 in /lib but in /usr/lib. I guess you're using conflicting packages from other sources.

I don't get it. I have tried it with all combinations of libgdal in-not in /lib and also in-not in /usr/lib. I have removed it completely from my system to let qgis install its own dependency of gdal, thinking that if qgis needs gdal.so.30 it should install it. And it does--in both /lib and /usr/lib! In both cases libgdal.so.30 is a symlink to libgdal.so.30.0.1.

I still get this symbol error for libgdal.so.30 which results in qgis-providers not being configured which then cascades to qgis, qgis-plugin-grass, and python3-qgis.

combinations? Above gdal comes from stock ubuntu. Are your versions the versions above?

[havenerk]

Yes. If I remove libgdal.so.30 symlink and libgdal.so.30.0.1 from both /lib and /usr/lib, the QGIS install puts them back in both places, symlinking /usr/libgdal.so.30 --> /usr/libgdal.so.30.0.1 and /lib/libgdal.so.30 --> /lib/libgdal.so.30.0.1. If I remove qgis, then autoremove, all instances of libgdal.30.so go away, so I'm pretty sure it is qgis doing the deed, and not some other dependency installing it on my system.

Looking through 'apt list', all libgdal related packages are 3.4.1+dfsg-1build4 amd64 except libgdal-grass/jammy 3.4.1-3 amd64.

Thoughts?

[jef-n]

Thoughts?

apt-cache policy qgis-providers libgdal30 libopenjp2-7:amd64

The symlinks in /lib are normal. QGIS needs GDAL, so it pulls it in as dependency. But it doesn't ship it's own GDAL - what you see is ubuntu's GDAL - and opj_encoder_set_extra_options is from libopenjp2-7. I guess gdalinfo would yield the same error.

[enzedrailmaps]

I have been successfully able to install both the LTR version and the packages from the Ubuntu repository on 22.04. Have you tried either of those?

[enzedrailmaps]

Make sure you have updated Ubuntu before you attempt an installation. It is not considered to be stable until the first point release comes out.

Hello Mr Github-actions bot,

No, it is still happening. To answer a few comments above. Ubuntu is up to date, who knows if it is 22.04.1? I update at least once a week. I can neither install the Ubuntu repository version, nor the qgis.org version (see below). 3.22.x was working on Ubuntu 21.10. They fail at exactly the same place, trying to configure qgis-providers and for the same reeason /usr/lib/qgis/crssync complaining about /lib/libgdal or /usr/lib/libgdal depending on who knows what. Apt seems to install libgdal.so.30.0.1 in both places (There is also a /lib/qgis and /usr/lib/qgis with identical content. Why?)

Is Ubuntu's libgdal/libopenjp2-7 broken for Ubuntu 22.04? I don't know how to test that.

Bottom line, QGIS will not install on Ubuntu 22.04 for me.

@havenerk I'm fall in the same issues because of a local build of gdal, I solve it by sudo rm -f /var/lib/dpkg/info/qgis-providers Then sudo apt update sudo apt upgrade All works fine

I cannot install qgis-providers from 3.22 ltr, 3.24, and now 3.26

The most relevant comment I've received so far is from jef-n on May 23 above. The problem is uninstalling libopenjp2-7 and reinstalling it would also uninstall a metric crap-ton of dependencies that I could probably not recover from, including ubuntu desktop. His comment about gdalinfo is also correct. So what do I do about libopenjp2-7? Why is it different in my setup vice everyone else's who has moved to ubuntu 22.04?

[Antoviscomi]

@havenerk in mine 22.04 I have libopenjpeg 8.0, after kernel update, then I rebuiltd gdal and I solved all dpkg configuration issues. (This because of a local build of gdal it uses the installed version of libopenjpeg)

[enzedrailmaps]

I have done multiple installs of Qgis LTR onto Ubuntu 22.04 and there was an issue every time. However, apt upgrade or apt full-upgrade fixed each problem as they happened. Using the project's packages rather than the Ubuntu ones. Last install I did was a week ago onto a computer that had just been upgraded in place from 20.04 to 22.04.0 As 22.04.1 has now been released maybe they have addressed this.

[enzedrailmaps]

Are you using apt full-upgrade as well as apt upgrade. Ubuntu has only just reached 22.04.1 which is the official public release of 22.04 LTS, before that it was still in beta.

[havenerk]

Still no bueno. My 22.04 is upgraded weekly so I have no idea what 22.04.x point release I may be on at any given time. I do use the project's packages rather than Ubuntu's. I have no idea what libopenjpeg8 is--it isn't available, so maybe a typo in that comment. I did check to see if there was a new libopenjp2-7 and there is but it makes use of "opj_encoder_set_extra_options" as well so would likely break gdal and qgis-providers as well. I am a meteorologist/climatologist and it is possible that some grib2 tool installed the culprit libopenjp2-7 library, but most of those tools use the jasper libraries instead. Sudo apt remove libopenjp2-7 reveals several gnome, gnome-desktop, ubuntu-desktop, and libreoffice dependencies in addition to the qgis ones, so it probably wasn't one of my specialty tools that did the deed.

[Antoviscomi]

@havenerk sorry for mistake, I meant libopenjpeg 8.0

[gioman]

Still no bueno

@havenerk still looks like a local issue and not a general one.

[havenerk]

Setting up qgis-providers (1:3.26.2+36jammy) ... /usr/lib/qgis/crssync: symbol lookup error: /lib/libgdal.so.30: undefined symbol : opj_encoder_set_extra_options dpkg: error processing package qgis-providers (--configure): installed qgis-providers package post-installation script subprocess returned e rror exit status 127 dpkg: dependency problems prevent configuration of qgis: qgis depends on qgis-providers (= 1:3.26.2+36jammy); however: Package qgis-providers is not configured yet.

So I removed (and autoremoved) all qgis and gdal packages, installed qgis and still get this error. I think my previous discussion of libopenjp2 was a red herring as I can find no dependencies of that library in the release files. @gioman, I would not call this a local issue because the error message is clearly impossible to reconcile--QGIS installs both of the conflicting libraries. Before I install, those libraries simply do not exist on the target machine. Afterward both are present and the error condition presents itself. But yet the conflict does not present on other machines, even another one of mine. The good machine is older, and AMD based, but both are bog standard unimpressive HP laptops and both started out as impish to jammy upgrades. Of course both upgrades uninstalled qgis, which I then re-installed or have at least attempted to.

[jef-n]

As said before it's not a QGIS problem. GDAL comes from an other source (eg. Ubuntu) and that depends on openjp2 and misses a symbol on your machine. QGIS installs fine on a fresh jammy. Probably some local leftovers from upgrades on your machine. I suppose GDAL is inoperable on your box too whether you install QGIS or not.

[havenerk]

Yes, gdal is broken when I install gdal-bin as a standalone program.

[Antoviscomi]

@havenerk can you try to install libopenjpeg 8.0? In my case all works fine after this library installation

[havenerk]

@antoviscomi, I can find no such package (libopenjpeg 8. I already have libjpeg8 installed (and also libjpeg9).

[Antoviscomi]

@havenerk sorry for mistake you're right, the package is libjpeg 8.0, however only one version of this must be installed 8 or 9, double version installed, create conflict with gdal

[havenerk]

@Antoviscomi I removed libjpeg9 to no effect. Still getting the same error. Reinstalled libjpeg8, also to no effect. I've asked the same question on the gdal git page. Maybe someone there knows what could be causing the conflict.

[jef-n]

opj_encoder_set_extra_options is new to openjpeg 2.4.0. I guess you have (possibly leftovers of) an earlier version around that GDAL for some reason picks up.

How it looks like here on a fresh jammy:

# ldd /usr/bin/gdalinfo  | grep openjp

SOLVED. Thank you @jef-n. My clumsy attempt with ldd didn't show anything, but when I invoked your command, I found a stray /usr/local/lib version of openjp2 version 2.3.0. I expect it was part of some meteorology software that I'd installed. Was not present on the one system that worked.

[damiandixon]

I found uninstalling gdal-bin and reinstalling qgis sorted this issue for me.

qgis has a dependency on libgdal-grass

[jef-n]

qgis has a dependency on libgdal-grass

QGIS doesn't need grass support in GDAL.

[idantene]

@havenerk what was your solution? I'm running into similar issues but it cites

/usr/lib/qgis/crssync: error while loading shared libraries: libproj.so.19: cannot open shared object file: No such file or directory

As the issue (which makes sense, since I have libproj22 installed, which is also the requirement -- not sure why it's looking for libproj.so.19).

[havenerk]

In my case I found an earlier version of a library in /use/local/lib which was earlier In my library path. The library was superfluous to needs and was replaced by a newer GDAL version in the QGIS, that was never found because it found the old version in my executable/LD path first. You can change the order in your path to execute /use/lib before /usr/local/lib.

Bottom line: find the old library and remove it or change the order of your executable/library paths.

Thanks for clarifying @havenerk! I cleared many of those, but no matter what I do, I do not have libproj.so.19 anywhere, and have no idea why it's needed specifically...

Creating a link results in undefined symbols as well, so I'm a bit stumped now 🤔

[havenerk]

In one of the previous answers to my problem there was a way to execute GDAL and see what libraries it was linking, or maybe it was an apt or an ld-related command, but that pesky library is somewhere on your path I bet. Good hunting

Thanks @havenerk! I managed to resolve the issue, and for what it's worth (for potential future troubleshooters), here's the rundown on my end:

1. I install gdal/proj/geos manually at some point in a past life. Can't recall which, doesn't really matter.
2. Following this thread, and specifically this comment, I realized that apt install installs to /usr/lib/x86_64-linux-gnu/.
3. At the same time, I realized that a manual installation puts files into /usr/local/lib/, where I found some older version of e.g. libgdal and libgeos.
4. Those libraries were found prior to the /usr/lib ones - I removed those with a simple rm /usr/local/lib/libg*
5. ??
6. Profit

Running into a similar problem on Ubuntu Jammy 22.04. QGIS (either 3.28 or 3.26.1 from the Software Store) will not install. And I removed a fully functioning version of 3.26.1 so now I have nothing. Here is the IO from

[Antoviscomi]

@paddleman I solve it by removing all qgis info files by `sudo rm /var/lib/dpkg/info/qgis`

then

sudo apt update
sudo apt upgrade

or (in your case)

sudo apt install qgis

[havenerk]

Check your path/LD path. That old lib is probably in it somewhere and it finds it first and then errors out. I think I found my problem library in /usr/local/lib which comes before /lib and /usr/lib in my path. I had installed something research-ish outside the normal QGIS and ubuntu installation process, long since removed, but it left that old library. Maybe just change the order of your path to get it installed if that turn out to be the problem. There is a command to find the location of the dependencies (it's in this thread somewhere) that pointed to the location of the offending library. Good luck.

@havenerk https://github.com/havenerk what was your solution? I'm running into similar issues but it cites

/usr/lib/qgis/crssync: error while loading shared libraries: libproj.so.19: cannot open shared object file: No such file or directory

As the issue (which makes sense, since I have libproj22 installed, which is also the requirement -- not sure why it's looking for libproj.so.19).

I also met this error while installing qgis on Ubuntu 22.04, and my solution is to install and use qgis in the conda environment. For details, please refer to https://gisunchained.wordpress.com/2019/05/29/using-qgis-from-conda/.

download sqlite-autoconf-${current_version}.tar.gz version no amalgamation

tar -xvf sqlite-autoconf-3420000.tar.gz

cd sqlite-autoconf-3420000/

gedit sqlite3.c

edit first macro definitions lines and add define SQLITE_ENABLE_COLUMN_METADATA 1 like this

#ifndef SQLITE_TCLAPI
#  define SQLITE_TCLAPI
#  define SQLITE_ENABLE_COLUMN_METADATA 1
#endif

save and make install

./configure

if the installation is corrupted retry

sudo apt install qgis qgis-plugin-grass

Try it, it worked here sudo apt purge libgeos-c1v5

Try removing ALL gdal packages and reinstalling first gdal-bin and libgdal-dev and lastly qgis

@paddleman I solve it by removing all qgis info files by sudo rm /var/lib/dpkg/info/qgis then sudo apt update sudo apt upgrade or (in your case) sudo apt install qgis

Nice and simple solution. Thanks

Try it, it worked here sudo apt purge libgeos-c1v5

Try removing ALL gdal packages and reinstalling first gdal-bin and libgdal-dev and lastly qgis

In mine I should need to rebuild gdal, because of a local build version, so this solution is useful for those have a classic installation
