Source: v4l2loopback Version: 0.12.1-1 Severity: serious X-Debbugs-CC: debian...@lists.debian.org User: debian...@lists.debian.org Usertags: issue Control: affects -1 src:linux-latest
Dear maintainers,
With a recent upload of linux-latest the autopkgtest of v4l2loopback
fails in testing when that autopkgtest is run with the binary packages
of linux-latest from unstable. It passes when run with only packages
from testing. In tabular form:
pass fail
linux-latest from testing 106
v4l2loopback from testing 0.12.1-1
versioned deps [0] from testing from unstable
all others from testing from testing
Currently this regression is blocking the migration of linux-latest to
testing [1], but I'll tell the migration software to ignore this
failure, as it seems to me that your package is broken when the latest
linux kernel isn't equal to the kernel running your test. I copied some
of the output at the bottom of this report. For your first test, if this
really can't be fixed and this installation is supposed to fail, I
suggest you mark the first test with the skip-not-installable
restriction. Maybe the second test should be marked as skippable as well
(I don't know, but you'll need to make it exit with code 77 in the
skippable situation).

[0] You can see what packages were added from the second line of the log
file quoted below. The migration software adds source package from
unstable to the list if they are needed to install packages from
linux-latest/106. I.e. due to versioned dependencies or breaks/conflicts.
