[Bug 1528378] Re: Possibly-bogus error about missing dkms.conf file during autoremove
I used strace on apt-get and it attempted to access the following non-
existent files:
/var/lib/dkms/vboxhost/5.0.9/source/dkms.conf
/var/tmp/mkinitramfs_OcRxJk/etc/modprobe.d/dkms.conf
The file /var/lib/dkms/vboxhost/5.0.9/build/dkms.conf DOES exist, but
was NOT accessed.
The file /usr/share/virtualbox/src/vboxhost/dkms.conf exists and WAS accessed successfully, and
it contains the same content as /var/lib/dkms/vboxhost/5.0.9/build/dkms.conf except for PACKAGE_VERSION
(which is older in the latter, not-accessed file).
=> Can someone who know how dkms works comment on this? Where is the problem likely to be?
(I could not see into /var/tmp/mkinitramfs_OcRxJk because that temp dir was removed)

Title:
Possibly-bogus error about missing dkms.conf file during autoremove
Status in One Hundred Papercuts:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
Updating the kernel, or anything which requires rebuilding initramfs
(including "apt-get autoremove") produces error messages like this:
run-parts: executing /etc/kernel/postinst.d/dkms 4.2.0-19-generic /boot/vmlinuz-4.2.0-19-generic
Error! Could not locate dkms.conf file.
File: does not exist.
But dkms seems to be working fine -- virtualbox modules get rebuilt as
they should be. There might be some other package which is broken
with respect to dkms.conf, but the message gives no hint about where
to look.
I tried to figure out where the message is coming from, but got no hits (other than log files) from
# find /boot /etc /lib* /bin /sbin /usr /var -type f -print0 | xargs -0 zgrep -l 'Error.*Could not locate'
I will attach /var/log/apt/term.log
ACTUAL RESULTS:
Error saying dkms.conf is missing
EXPECTED RESULTS:
No error, or else an error which indicates which module is broken or the path of the missing file
(If the underlying problem is not in the above postinst script, but in
another module which produces the un-useful iagnostic, please redirect
this bug to that package).
