package samba-common-bin 2:4.11.6+dfsg-0ubuntu1.3 failed to install/upgrade: installed samba-common-bin package post-installation script subprocess returned error exit status 1

[Bryan Henry]

I was able to workaround the installation failure by using systemd-tmpfiles to create the missing directory:

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

Specifically samba 2:4.11.6+dfsg-0ubuntu1.3 does ship /usr/lib/tmpfiles.d/samba.conf that creates /run/samba. This works correctly for me in a quick test, including after a reboot. It's not clear to me why this isn't working for you, and you haven't provided full steps to reproduce your issue.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.

The pathway by which this error can occur, is installing package "samba-common-bin" on focal20.04 with no previous samba installation ... -- although there is a /usr/lib/tmpfiles.d/samba.conf installed, the package installer seems to end up creating the above error due to not having /run/samba when trying to start something samba-related using smb.conf provided in samba-common...
Appears, this particular state can be workarounded by manually creating /run/samba then installing samba-common-bin, then on next reboot /run/samba is created automatically and error does not recur...

[Robie Basak (racb)]

Sorry, I still cannot reproduce this. I tried:

lxc launch ubuntu:focal samba
lxc exec samba bash
apt update
apt install samba-common-bin

...and this succeeded as expected. Please could you provide exact steps to reproduce this problem?

After messing around with a bunch of permutations of installing/uninstalling/purging various samba components, and removing/creating various config dirs and files, I notice this set of steps seem to produce *a* error similar to what's reported, although it's not giving exactly the same error output:

$ sudo apt-get install samba
$ sudo apt-get remove --purge samba-common-bin
$ sudo rm -rf /run/samba
$ sudo rm -rf /etc/samba
$ sudo apt-get install samba-common-bin
Reading package lists... Done

E: Sub-process /usr/bin/dpkg returned an error code (1)

(To get the system back after this, run: sudo apt-get remove --purge *samba*; sudo apt-get install samba)

I don't seem to get the errors about the missing /run/samba directory, but wonder if that is due to an unrelated configuration issue? In any case there seems to be a matching debian report here:

sudo apt-get remove --purge
*samba*; sudo apt-get install samba

I applied this recommendation without error; thank you
