[Bug 1954724] Re: Removing unattended-upgrades removes ubuntu-server-minimal

[Matthew Ruffell]

** Description changed:

  On Impish and later, removing unattended-upgrades also removes ubuntu-
  server-minimal due to ubuntu-server-minimal depending on unattended-
  upgrades
  
  $ sudo apt remove unattended-upgrades
  ...
  The following packages will be REMOVED:
-   ubuntu-server-minimal unattended-upgrades
+   ubuntu-server-minimal unattended-upgrades
  0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
  
  This behaviour has changed since ubuntu-meta 1.471 [1] when the ubuntu-
  server-minimal metapackage was introduced, declaring unattended-upgrades
  as Depends.
  
  [1] https://launchpadlibrarian.net/550345392/ubuntu-
  meta_1.470_1.471.diff.gz
  
  On Focal, there was no such behaviour on a fresh ubuntu-server install:
  
  $ sudo apt remove unattended-upgrades
  ...
  The following packages will be REMOVED:
-   unattended-upgrades
+   unattended-upgrades
  0 upgraded, 0 newly installed, 1 to remove and 9 not upgraded.
  
  Removing unattended-upgrades is quite popular amongst our users, and
  they should be allowed to remove the package without removing the
  ubuntu-server-minimal metapackage.
  
  Looking at the source package for ubuntu-meta, unattended-upgrades is
  only Depends for ubuntu-server-minimal, maybe we should simply remove
- it?
+ it, or instead, change to recommends?
  
  $ grep -Rin "unattended-upgrades" .
