> The comment at https://github.com/fwupd/fwupd/issues/3037#issuecomment-1100816992 suggests that disabling the DynamicUser= setting makes the service work again. Maybe that's worth a try, in order to get both problems solved? (i.e. shipping an override config for fwupd)
> $cat /etc/systemd/system/fwupd-refresh.service.d/override.conf > [Service] > DynamicUser=no The whole point of using DynamicUser in this case was so that fwupdmgr didn't run as root when it reached out to the web to get data. Yes, certainly turning off DynamicUser in fwupd-refresh.service will solve the problem, but that is then a different threat vector. I think if turning off DynamicUser=1, then we probably need to also create a new service account for that systemd service to use. I'll open a new bug to move this discussion to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1969976 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1871538 Title: dbus timeout-ed during an upgrade, taking services down including gdm Status in D-Bus: Unknown Status in systemd: New Status in accountsservice package in Ubuntu: Invalid Status in dbus package in Ubuntu: Invalid Status in gnome-shell package in Ubuntu: Invalid Status in systemd package in Ubuntu: Fix Released Status in accountsservice source package in Focal: Invalid Status in dbus source package in Focal: Invalid Status in gnome-shell source package in Focal: Invalid Status in systemd source package in Focal: Fix Released Status in accountsservice source package in Groovy: Invalid Status in dbus source package in Groovy: Invalid Status in gnome-shell source package in Groovy: Invalid Status in accountsservice source package in Hirsute: Invalid Status in dbus source package in Hirsute: Won't Fix Status in gnome-shell source package in Hirsute: Invalid Status in accountsservice source package in Impish: Invalid Status in dbus source package in Impish: Invalid Status in gnome-shell source package in Impish: Invalid Status in systemd source package in Impish: Fix Released Status in accountsservice source package in Jammy: Invalid Status in dbus source package in Jammy: Invalid Status in gnome-shell source package in Jammy: Invalid Status in systemd source package in Jammy: Fix Released Bug description: [Impact] * There's currently a deadlock between PID 1 and dbus-daemon: in some cases dbus-daemon will do NSS lookups (which are blocking) at the same time PID 1 synchronously blocks on some call to dbus-daemon (e.g. `GetConnectionUnixUser` DBus call). Let's break that by setting SYSTEMD_NSS_DYNAMIC_BYPASS=1 env var for dbus-daemon, which will disable synchronously blocking varlink calls from nss-systemd to PID 1. * This can lead to delayed boot times * It can also lead to dbus-daemon being killed/re-started, taking down other services with it, like GDM, killing user sessions on the way (e.g. on installing updates) [Test Plan] * This bug is really hard to reproduce, as can be seen from the multi-year long discussion at https://github.com/systemd/systemd/issues/15316 * Canonical's CPC team has the ability to reproduce this issue (with a relatively high probability) in their Azure test environment, due to the specific setup they are using * So our test plan is to ask CPC (@gjolly) for confirmation if the issue is fixed. [Where problems could occur] * This fix touches the communication between systemd and dbus daemon, especially the NSS lookup, so if something is broken the (user-)name resolution could be broken. * As a workaround dbus-daemon could be replaced by dbus-broker, which never showed this issue or the behaviour could be changed back by using the `SYSTEMD_NSS_DYNAMIC_BYPASS` env variable, like this: #/etc/systemd/system/dbus.service.d/override.conf [Service] Environment=SYSTEMD_NSS_DYNAMIC_BYPASS=0 [Other Info] * Fixed upstream (v251) in https://github.com/systemd/systemd/pull/22552 === Original Description === This morning I found my computer on the login screen. But not the one of the screen log, no a new one - so something must have crashed. Logging in again confirmed that all apps were gone and the gnome shell was brought down what seems like triggered by a background update o accountsservice. As always things are not perfectly clear :-/ The following goes *back* in time through my logs one by one. Multiple apps crashed at 06:09, but we will find later that this is a follow on issue of the underlying gnome/X/... recycling. -rw-r----- 1 paelzer whoopsie 52962868 Apr 8 06:09 _usr_bin_konversation.1000.crash -rw-r----- 1 paelzer whoopsie 986433 Apr 8 06:09 _usr_lib_x86_64-linux-gnu_libexec_drkonqi.1000.crash rdkit was failing fast and giving up (that will be a different bug, it just seems broken on my system): Apr 08 06:10:13 Keschdeichel systemd[1]: Started RealtimeKit Scheduling Policy Service.
