The fix is not easy to confirm since it's random and the errors report are against services using it like gdm so the 'version it's happening with table' don't tell us what version of e.g gdm was in use and not accountsservice
The updated 0ubuntu12~20.04.1 version works without visible problems though and the fix is simple and got upstream reviewed. There are also no regression reported Based on those facts I'm going to mark the SRU as verified ** Tags removed: verification-needed verification-needed-focal ** Tags added: verification-done verification-done-focal -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to accountsservice in Ubuntu. https://bugs.launchpad.net/bugs/1843982 Title: Various programs crashed with SIGSEGV in g_str_hash() from g_hash_table_lookup() from update_user() Status in accountsservice: Fix Released Status in accountsservice package in Ubuntu: Fix Released Status in accountsservice source package in Focal: Fix Committed 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. Update to this SRU, and then *restart your system*. The crash is in the library part, and so you will still see it if programs loaded the buggy version. Restarting is the easiest way to make sure you're not on it. 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.
