I can reliably reproduce this: 1. Inside several aarch64 systemd-machined containers (with PrivateUsers=0 in nspawn conf) with focal and running Gnome Shell session (accessed via TigerVNC server). Hosts in NanoPC-T4. 2. On one bare metal NanoPC-T4 host with focal, running Gnome Shell Wayland session. No container/virtualization stuff, only bare metal.
Symptoms looks the same? ~$ sudo /usr/libexec/rtkit-daemon --stderr rtkit-daemon[5786]: Successfully called chroot. rtkit-daemon[5786]: Successfully dropped privileges. rtkit-daemon[5786]: Successfully limited resources. rtkit-daemon[5786]: pthread_create failed: Resource temporarily unavailable rtkit-daemon[5786]: Demoting known real-time threads. rtkit-daemon[5786]: Demoted 0 threads. With --no-drop-privileges it works: ~$ sudo /usr/libexec/rtkit-daemon --stderr --no-drop-privileges rtkit-daemon[5781]: Successfully called chroot. rtkit-daemon[5781]: Successfully limited resources. rtkit-daemon[5781]: Running. rtkit-daemon[5781]: Canary thread running. rtkit-daemon[5781]: Watchdog thread running. However, in both cases I have to use Armbian kernel. For the record, on RPi3B running generic Ubuntu 20.04 aarch64 image (boot via UEFI) this issue is not reproducible. I can help with further debug here, or my issue is different and I have to go to Armbian forum? In the former case what exactly I need to de to help debug this? ** Changed in: rtkit (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rtkit in Ubuntu. https://bugs.launchpad.net/bugs/1871543 Title: rtkit fails to start in focal "pthread_create failed: Resource temporarily unavailable" Status in rtkit package in Ubuntu: Confirmed Bug description: I was debugging something else and found rtkit broken on my system.
