Hello Hans-Petter, or anyone else affected,

Accepted accountsservice into focal-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/accountsservice/0.6.55-0ubuntu12~20.04.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Various programs crashed with SIGSEGV in g_str_hash() from
  g_hash_table_lookup() from update_user()

Status in accountsservice:
  New
Status in accountsservice package in Ubuntu:
  Fix Released
Status in accountsservice source package in Focal:

Status in accountsservice package in Debian:
  Confirmed

Bug description:
  [ Description ]

  When accountsservice's daemon is restarted - particularly when there
  is a user configured for auto login - it can cause code using its
  library to crash. This is bad because gnome-shell is one of those
  users which crashes.

  [ QA ]

  Configure a user for automatic login in gnome-shell.

  Restart accounts-daemon.service (sudo systemctl restart accounts-
  daemon.service) a few times, leaving several seconds between each
  attempt.

  See that it crashes if you don't have this SRU, and doesn't if you do
  have it.

  ---

  Test that fast user switching still works properly.

  ---

  Take a look at the error reports listed below and hopefully see them
  not occurring (barring the usual noise) with the SRU.

  [ Regression potential ]

  We think this is safe - it tells clients that the daemon is away when
  it quits, and is back when it comes back. They should get appropriate
  signals to indicate this. Nevertheless, these signals are sent when
  they weren't before now, so that could cause problems. Watch out for
  errors creeping up with this SRU.

  We wondered upstream whether some more protections might be needed.
  I'm thinking that those should be *additional* safety rails around
  this fix, but it could actually be that more is needed and this fix
  isn't complete.
