    Somehow my production server got 'resolvconf' removed during the night (which caused some problems).

    Here is the apt log for the specific time:

    2024-08-07 06:44:00 startup packages configure
    2024-08-07 06:44:23 startup packages remove
    2024-08-07 06:44:23 status installed resolvconf:all 1.84ubuntu1

    2024-08-07 06:44:27 status not-installed resolvconf:all <none>
    2024-08-07 06:44:27 startup packages configure
    2024-08-07 06:44:34 startup archives unpack
    2024-08-07 06:44:34 upgrade containerd.io:amd64 1.6.21-1 1.6.31-1
    2024-08-07 06:44:34 status half-configured containerd.io:amd64 1.6.21-1
    2024-08-07 06:44:34 status unpacked containerd.io:amd64 1.6.21-1
    2024-08-07 06:44:34 status half-installed containerd.io:amd64 1.6.21-1
    

    It was not happening at Cloudron 7.* bug only happened on Cloudron 8.*

    It feels like some automatic removal has been added recently. If so - how do I make sure it's not running?

      I hope that marking the package on hold would work fine, i.e.:

      apt install resolvconf
      apt-mark hold resolvconf

        @potemkin_ai resolvconf is not needed anymore and is uninstalled by the update. Installing it causes confusion with dns resolution . With Cloudron 8, systemd-resolved (the ubuntu default) is used for DNS resolution . So, it should remain uninstalled. Are you having any problems with DNS resolution ? You can check the output of resolvectl to see if nameservers are being assigned correctly .

          I need it for wireguard. Re-installed it back and it seems to be holding up so far. What kind of issues would you expect, if you are not using it?

            @potemkin_ai resolvconf was only previously needed because we replaced the system DNS resolution with unbound. As for issues, the usual disclaimer about installing additional packages having unintended side effects on future versions of Cloudron applies.

              @joseph well, right. I understand necessity to keep focus for the product.
              But that limits the application of Cloudron quite significantly.

              Am I right in understanding that I can not rely on any software - part of Cloudron setup, even on OS level?

                @potemkin_ai yes, there is no guarantee that software that is pre-installed with Cloudron today will be available in the next release.

                  @joseph Ok. Minor releases and major releases - all the same? Or may I not worry inside major release - which is 8 now?

                    @potemkin_ai currently, we have no policy on this. but yes, patch releases won't remove ubuntu packages unless a security fix demands it.

                        For the future generations: better do ln -s /usr/bin/resolvectl /usr/local/bin/resolvconf to avoid messing with system's and cloudron settings

                        Or use netplan's WireGuard capabilities.
