Ubuntu 20.04 systemd install failure

[tarzanek]

I know 20.04 is not supported but install works, up until it comes to scylla-jmx:

Unpacking scylla-jmx (4.0.1-20200524.530232f8c19-1) ...
dpkg: error processing archive /tmp/apt-dpkg-install-65xVuf/18-scylla-jmx_4.0.1-20200524.530232f8c19-1_all.deb (--unpack):
 unable to open '/usr/lib/systemd/system/scylla-jmx.service.dpkg-new': No such file or directory
No apport report written because the error message indicates an issue on the local system

this is just FYI, since after that deb packaging seems to get broken beyond repair (above package cannot be removed, nothing else can be installed) @syuu1228 ping

[tarzanek]

Workaround (and cleanup of above), if you don't mind having scylla-jmx:

apt -y remove scylla
apt -y install scylla-server

Does it work on 18.04?

[tarzanek]

I can test 18.04, but I have no reason to believe it shouldn't, since 18.04 is supported

[tarzanek]

confirming, 18.04 just works, 20.04 doesn't, so this needs to be addressed before we will support 20.04

[tarzanek]

How to repro: on 20.04 run:

sudo curl -o /etc/apt/sources.list.d/scylla.list -L <URL TO SCYLLA REPO>
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 5e08fbd8b5d6ec9c

sudo apt-get update
sudo apt-get -y install scylla

[avikivity]

I did reproduce it; I don't understand why it happens.

Experiencing the same issue on a Debian 10.4 machine. The suggested workaround works, but leaves it without the nodetool utility then.

[avikivity]

I think I see it.

should be /usr/lib, not /lib.

[toddwong]

In debian 10, /lib is a symbolic link to /usr/lib.

When dpkg unpack the files, it appends .dpkg-new to the file names. After all file unpacked, it then renames then one by one, but after the renmaming of /lib/systemd/system/scylla-jmx.service.dpkg-new, there won't be /usr/systemd/system/scylla-jmx.service.dpkg-new any more.

But I know very little about the dpkg things. I don't know why scylla-server.deb, which seems having the same issue, works.

@avikivity Seems like same bug fixed by https://github.com/scylladb/scylla-jmx/commit/2883a8dc63dca9944032143fb79ec3ae09a68ac1, but the commit seems like not backported to 4.0.1.

[avikivity]

I'll backport it.
