linux-kvm ADT test test_snapd_snap_with_vendored_apparmor failure with linux-kvm/5.15.0-1050.55

[Kevin Becker]

This is a scripted bug report about ADT failures while running linux-kvm tests for linux-kvm/5.15.0-1050.55 on jammy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

Testing failed on:
    amd64: https://autopkgtest.ubuntu.com/results/autopkgtest-jammy/jammy/amd64/l/linux-kvm/20240118_121042_1259e@/log.gz

As part of ubuntu_qrt_apparmor, we get the following error. This also seems to lead to further apparmor errors.
