casper autopkgtest failure with linux 5.8.0.30.32+21.04.34

[Andrea Righi]

The latest kernel in hirsute is going to be 5.8.0.30.32+21.04.34. With this kernel installed the autopkgtest for casper is failing with the following error:

  qemu: could not open kernel file '/boot/vmlinu*-5.8.0.30.32+21-04-generic': No such file or directory

The reason is that the "+21.04.34" sub-string in the kernel version isn't handled properly and it should be stripped off to determine the kernel file to use in /boot.

We should probably strip off everything after the "+" from the kernel version string, to properly support kernels that use this particular version format.

Debdiff in attach seems to fix the problem.

This bug was fixed in the package casper - 1.456

---------------
casper (1.456) hirsute; urgency=medium

  * Support kernels with "+" in the version string (LP: #1905357).
