[Bug 1955859] Re: ubuntu-base on jammy daily: apt-key has no access to /dev/null

Tue Dec 28 09:23:55 UTC 2021

Thanks for your bug report. I believe you meant ubuntu-base, not ubuntu-
core (the snap based one)

How did you test this? This seems to me like you forgot to populate
/dev, either statically or by bind mounting the /dev from the host.

The tarball only contains an empty /dev, and the permissions have not
changed.

jak at jak-t480s:~/Downloads$ tar tvzf jammy-base-amd64.tar.gz  dev
drwxr-xr-x root/root         0 2021-12-28 06:01 dev/
jak at jak-t480s:~/Downloads$ tar tvzf focal-base-amd64.tar.gz  dev
drwxr-xr-x root/root         0 2021-12-28 05:44 dev/

If APT had succeeded *creating* /dev/null as a regular files, all hell
would have broken lose, so I am kind of happy that did not happen.

For the record, the reason it fails with EPERM seems to be that it's
apt-key that's failing and it's run as the user _apt by apt.

** Summary changed:

- ubuntu-core on jammy daily: apt-key has no access to /dev/null
+ ubuntu-base on jammy daily: apt-key has no access to /dev/null

** Changed in: apt (Ubuntu)
       Status: New => Incomplete

** Also affects: ubuntu-qa-website
   Importance: Undecided
       Status: New

Title:
  ubuntu-base on jammy daily: apt-key has no access to /dev/null

Status in Ubuntu QA Website:
  New
Status in apt package in Ubuntu:
  Invalid

Bug description:
  Ubuntu Jammy Core - Smoke test fails.

  One of the issues that I believe may be the primary issue is that apt-
  key has no access to /dev/null.
