** Description changed: - When trying to uninstall a (customly built) DKMS module using "dkms - uninstall -m my_module -v 1.1" dkms fails with exit code 1 and doesn't - print an error message. - - The problem occurs with the invocation of the function "have_one_kernel" - in the /usr/sbin/dkms script. This function doesn't evaluate to 0 as it - should, when all conditions are met (as with the command specified - above). + [Impact] + This bug makes it impossible to uninstall DKMS modules. When trying to uninstall a DKMS module using "dkms uninstall -m my_module -v 1.1" dkms fails with exit code 1 and doesn't print an error message. The commands "dkms uninstall -m my_module -v 1.1 --all" and "dkms uninstall -m my_module -v 1.1 -k 3.2.0-57 -k 3.5.0-44" fail as expected with the resp. error messages and exit codes in function "have_one_kernel". + + The proposed patch is a backport from upstream. + + + [Test Case] + A test script has been added in comment https://bugs.launchpad.net/debian/+source/dkms/+bug/1261116/comments/8. + + To reproduce the bug: + 1.
