[hardy] /dev missing some entries, others have wrong permissions

[Rob Hughes]

Binary package hint: udev

After a dist-upgrade, i'm see the same as in this thread:

http://ubuntuforums.org/showthread.php?t=613758

I searched, but couldn't find a bug report. As of now, I can't start X due to a missing /dev/input/*, I have no sound, since the /dev/snd/* entries are missing. There's probably other things missing as well. I tried reverting to an old kernel where everything worked, but that made no difference. Installed version of udev is 117-3.

I confirm 660 permissions on /dev/{null,zero} and lots of other devices which should be accessible by my user. Also /dev/input/mice is gone and i needed to symlink it. This happened about a week ago after dist-upgrade from gutsy. This is a killer bug and I still haven't found the solution.

After reading this thread http://ubuntuforums.org/showthread.php?t=613758&page=2, the problem was solved for me. I suspect removing libsane-extras (and its according udev rules file) was the fix. I am not 100% sure though, as I did apt-get update just before rebooting now since I did not have time to look more closely into this. Also, removing libsane-extras using "apt-get remove" did not work, so I had to use dpkg --purge. FYI, YMMV.

Yep, looks like this whole mess is being caused by problems with libsane-extras.

[Rob Hughes (rob-robhughes)]

There, I changed the package name to match the true source of the problem.

I was having the same problem since I upgraded to hardy.
By purging libsane-extras everything works fine again, thank you. XD

I added a link to the debian bug for this issue. It is solved in version 1.0.18.14 in Debian.

The problem is that the udev rule uses the wrong name for a LABEL which makes the system unusable after installation of libsane-extras. This is serious since installing a package (even if is it from the universe respository) should not stop your system from booting.

Is it possible to sync with that Debian version, with regards to the feature freeze I mean? Or should I make a debdiff that only fixes this specific bug. Would be nice to have the fix before release of Hardy.

[Emanuel Steen (kozz)]

Attached a debdiff that fixes the problem. Only fixes the labels in the udev rules but should be an ok fix for Hardy to make the package not break the system :)

Uploaded, thanks ;)
I switched Maintainer field according to https://wiki.ubuntu.com/DebianMaintainerField and used LP: #180169 notation to close this bug automatically.

This bug was fixed in the package sane-backends-extras - 1.0.18.12ubuntu1
