None of snaps starts after upgrade to 24.04

snapd

Every snap I am trying to run after upgrading to Ubuntu 24.04 (from 23.10) hangs forever. Using strace I can see that it tries to open nonexistent bpf file:

access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0x7ffeed7ced50) = 0
access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0x7ffeed7ced50) = 0
access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0x7ffeed7ced50) = 0
access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0x7ffeed7ced50) = 0
access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=1, tv_nsec=0}, 0x7ffeed7ced50) = 0
access("/var/lib/snapd/seccomp/bpf//snap.hello-world.hello-world.bin2", F_OK) = -1 ENOENT (No such file or directory)

The contents of /var/lib/snapd/seccomp/bpf:

global.bin                    snap.firefox.hook.configure.bin                      snap.firefox.hook.post-refresh.src  snap.hello-world.sh.bin

snap.firefox.geckodriver.bin  snap.firefox.hook.disconnect-plug-host-hunspell.src  snap.hello-world.hello-world.bin
snap.firefox.geckodriver.src  snap.firefox.hook.post-refresh.bin                   snap.hello-world.hello-world.src

Any ideas?

Can you run systemctl status snapd.service and post the output? is the snapd.service reported as active?

Here you go

Apparently this just got fixed with today’s snapd update (snapd_2.63+24.04_amd64.deb). All good now
