Can't install on Ubuntu 16.04

[Sockolet]

I've successfully built the Debian package using the command that you provide in the readme.

But the result is a little bit weird. It gives a ~10MB file when a usual one is ~50MB. When I try to install it, it says something relating dependencies: libc6.0, libc6.1 and libc0.1. Is weird because I've got official emby 3.5.0 (and past versions) installed without any dependency warning. And it's more weird since I was using Carlos Hernandez's ppa in Ubuntu without issues which is the one that you refers on your readme.

Is there anyway to build the package for Ubuntu?

[joshuaboniface]

That size is right - my copy is 11M when build:

-rw-r--r--  1 joshua operator  11M Aug  9 01:16 emby-server_3.4.1.18-unlocked_all.deb

How are you installing the package? I assume dpkg -i? If so, can you try running apt -f install first, to see if that grabs the dependencies? If not, please post the full dpkg/apt output and I can provide some guidance!

[Sockolet]

If I run sudo apt -f install it does nothing. I can run it after the attempt of installation.

This is the output:

Here's official 3.5.0 package output (disregard 'service masked' warning):

PS: Ubuntu version is Ubuntu Server 16.04 fully updated.

[joshuaboniface]

Aah OK, so it's looking for one of 3 different names for the libc package, and finding none of them, specifically since the version in Ubuntu 16.04 is "too old". The specific relevant line is:

emby-server depends on libc6 (>= 2.27) | libc6.1 (>= 2.27) | libc0.1 (>= 2.27); however:
Version of libc6:amd64 on system is 2.23-0ubuntu10.

This gets set automatically during the package build automatically by this line in the debian/control file:

Depends: ${shlibs:Depends}, ${cli:Depends}, ${misc:Depends}, at, libsqlite3-0, mono-runtime (>= 5.14)

So it looks like something is wonky with the build environment. Unfortunately all my experience building Debian packages is on Debian itself, so I suspect there's just something weird in the way Ubuntu does it. Are you building it on an Ubuntu 16.04 machine as well?

[JustAMan]

My current approach yields a 23M-sized binary (that's 3.5.2 for netcore), on Debian 9. So 10 MB is definitely too small...

[joshuaboniface]

@JustAMan I found the 3.4.X builds to be quite a bit smaller - I think because it's not statically linking any dependencies. 3.5.X were a bit bigger when I was testing them out (closer to your 23M).

[Sockolet]

I'm building it on a different Ubuntu 18.04 machine. But I can try in the 16.04 itself for testing if it is necessary.

[joshuaboniface]

Yea that would do it. If you build the deb on 18.04 you're using the shared libraries of 18.04 as dependencies which aren't available on 16.04. You'd need to build the 16.04 package on a 16.04 machine.

[Sockolet]

Well, i was able to built successfully the deb package, and installed it without further issues. Now I'm facing another weird thing, because it looks like the service fails at startup:

Does anyone know where are the emby server logs stored?

[JustAMan]

By default they're under /var/lib/emby/logs You might not need those, though, it looks more like you have an issue with emby-server script.

Facing same problem after have purged any old configuration files:

I don't know if anyone can help me with this...

[JustAMan]

Do you have sqlite installed in your system? It seems that this managed wrapper fails to use the native version it should be wrapping.
