[Bug 1873794] Re: Unattended upgrades fixes missing from security repo

[Neil Wilson]

If the fix is not in the security pocket, how does it get sorted if the
updates pocket is turned off?

I understood *-updates are only supposed to be recommended.


As I mentioned if you build an image with a tool like 'mkosi' which utilises debootstrap and then cleans the cache, the partial directory is missing in the resulting image.

Under the Debian file system layout /var is supposed to be volatile. You
can't rely on anything being there.

Title:
  Unattended upgrades fixes missing from security repo

Status in unattended-upgrades package in Ubuntu:
  Fix Released
Status in unattended-upgrades source package in Xenial:
  Fix Released
Status in unattended-upgrades source package in Bionic:
  Fix Released
Status in unattended-upgrades source package in Eoan:
  Fix Released

Bug description:
  Critical unattended upgrades fixes are missing from the bionic
  security repo, which means that if you are using an installation of
  Ubuntu using only 'bionic' and 'bionic-security' you can stop
  unattended-upgrades from working just by doing a 'rmdir
  /var/cache/apt/archives/partial'.

  This is because the 'rootdir' parameter on the main function is set to
  "" rather than "/" - which disables the required directories and files
  check.

  I'm presuming here that the *-updates pocket is still 'recommended'
  rather than 'required'.
