Subscription-manager config overwritten after update on Ubuntu 22.04 system

Hey everyone,
(or especially hey @atix )

I just updated one of my Ubuntu 22.04 testsystems to the latest packages, and as well to the python3-subscription-manager package version from 1.28.24-8 to 1.29.35-1.
Noticed there, that it moved the working /etc/rhsm/rhsm.conf config to /etc/rhsm/rhsm.conf.dpkg-old, which basically made the upgrade fail, because it couldn’t do the package-profile-upload at the end of the upgrade anymore.
After I recovered the needed variables to the new config file (hostname, prefix, baseurl, repo_ca_cert) it’s working again, but yeah I don’t understand apt enough to know if they are doing this all the time or if this is a packaging thing that needs to be changed, that it creates dpkg-new files instead of moving the old config to dpkg-old?

If needed I can provide more information, not sure right now what might help here!

Thanks, Lukas!

Foreman and Proxy versions:

Foreman 3.7
Katello 4.9

Distribution and version:

Server: Rocky Linux 8.8
Client: Ubuntu 22.04 LTS

Looking into it, I would have had to define -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold", which is the default if ran via a job invocation, but is not the default when manually run on the system.

If there is no way to surpass this on the package level (or unwanted in the deb building world), welp then is it like that, coming from the RPM based world this is just different.

Hi Lukas :wave:

I could not reproduce this issue with the latest packaged subscription-manager for Ubuntu 22.04. Can you please retest this? Please resync and reinstall subscription-manager on your host.

I went from

Hey Maximilian,

thanks for your help :slight_smile:
Tbh it’s weird, fortunately I have backups and lots of automatic CV builds, so I rolled back to before the upgrade, switched to the old CV, reinstalled subscription-manager, switched back to the new CV, and now it happened like it would be expected! :

Setting up python3-subscription-manager (1.29.35-1) ...

Configuration file '/etc/rhsm/rhsm.conf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** rhsm.conf (Y/I/N/O/D/Z) [default=N] ? 

Was missing this part before the restore/reinstall! So yeah… I don’t know what was happening there, but obviously apt was thinking it’s fine to not ask.
Thanks for testing though :slight_smile:

Cheers, Lukas
