Title:
Upgrading 12.04 to 14.04 pam issues
Status in Ubuntu:
New
Bug description:
Upgraded 12.04 to 14.04 and lost sound, printing, software center
install privilege, etc.
(Most similar bug I could find was: Bug #1317518 )
After upgrading from 12.04 to 14.04, I noticed:
--I couldn't print on 14.04, but yesterday I could print on 12.04. But
there were now many more network printers available for use than with
12.04. I was able to print from a network printer, just not from USB
printer that I could print from in 12.04 (didn't toubleshoot further)
--I had no sound on boot/login nor on a Youtube video presentation. read some forums and tried some suggestions such as:
cp /usr/share/sounds/ubuntu/stereo/* /usr/share/sounds/ My main observation was that the only sound device available from Sound Preferences was something I had never seen called "Dummy Output". With 12.04 there were usually a few like Alsa, etc. I read forums on this and suggestion was to install "PulseAudo Preferences".
--But when I tried installing the sound preferences app, the error msg
said "Authentication Error" : "Software can't be installed or removed
because the authentication service is not available.
(org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name':
':1.108'}): org.debian.apt.install-or-remove-packages" Followed by
"You are not allowed to perform this action" : "ou don't have the
required privileges to perform this action." But I am the admin/root
user. I rechecked under System Tools -> System Settings -> User
Accounts My account type is " Administrator"
--I also tried mounting some other partitions that were still
available in the "Places" menu tab (I use the classic gnome UI, which
14.04 remembered from 12.04). I used sudo mount ... and was asked for
password, not nothing ever mounted.
"uname -a" prints:
Linux my-username-GA-MA785GM-US2H 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
What I think should happen is sound and printing should work and when
I click on the unmounted partitions in the Places l ist they should
mount as they did in 12.04. I should also be able to use the Software
center to install apps/packages (although I usually prefer the CLI and
apt-get)
First asked for assistance on answers.launchpad.net. See Question #253289

Workaround involved finding a similar bug in the 13.04 to 13.10 upgrade that was fixed by these steps:
1. sudo pam-auth-update --force
2. adding the following to lines to a previously empty file named /etc/pam.d/lxdm
session required pam_loginuid.so
session required pam_systemd.so
3. rebooting
Don't know if there is a better fix. I tried only step one at first
but it did not help. Don't know whether step two by its self could fix
it or not.
