I am running Ubuntu 14.04.3 32bit OS. A few months ago I wanted to install QTCAM from source which
it requires systemd library files.
As you know 14.04 Ubuntu doesn't use systemd yet, so, as the author said
I compiled and installed systemd218 version of it.
I set prefix a local path not to mess up system configuration. I compiled and installed it.
On the next boot it failed to log in to default user session. It failed to gain access to ~/.cache
directory.
When I remove it by logging in to text mode then I can log in to default user session.
After logging in I tried many things to fix it. I did sudo make uninstall
from systemd218 source folder hoping that it would roll back the changes but nothing happened.
I reinstalled all pam related packages.
I ran sudo pam-auth-update
to fix authorization problems.
I visited many forums and read bug reports. Though my problem stemmed from a known reason, I met many similar symptoms without a common fix.
I found shared libraries installed by systemd218 in systemd218 source directory like
find -name *.so
./.libs/id128.so
./.libs/_journal.so
./.libs/_reader.so
./.libs/libgudev-1.0.so
./.libs/_daemon.so
./.libs/login.so
./.libs/libsystemd.so
./.libs/pam_systemd.so
./.libs/libudev.so
and reinstalled every package contains those from synaptic.
I also located conf files, they are lots.
find -name *.conf
./sysusers.d/basic.conf
./sysusers.d/systemd.conf
./sysusers.d/systemd-remote.conf
./src/timesync/timesyncd.conf
./src/core/org.freedesktop.systemd1.conf

./tmpfiles.d/systemd-nologin.conf
./tmpfiles.d/tmp.conf
./tmpfiles.d/systemd.conf
./tmpfiles.d/legacy.conf

Most important ones must be udev rules. I think one of them broke my system.
find -name *.rules
./src/login/71-seat.rules
./src/login/73-seat-late.rules
./src/login/70-uaccess.rules
./src/login/70-power-switch.rules
./src/vconsole/90-vconsole.rules
./rules/60-persistent-serial.rules
./rules/60-persistent-alsa.rules
./rules/80-net-setup-link.rules
./rules/61-accelerometer.rules
./rules/50-udev-default.rules
./rules/60-persistent-input.rules
./rules/80-drivers.rules
./rules/60-persistent-storage-tape.rules
./rules/75-probe_mtd.rules
./rules/75-tty-description.rules
./rules/70-mouse.rules
./rules/60-cdrom_id.rules
./rules/95-udev-late.rules
./rules/60-drm.rules
./rules/42-usb-hid-pm.rules
./rules/75-net-description.rules
./rules/99-systemd.rules
./rules/60-persistent-v4l.rules
./rules/60-keyboard.rules
./rules/64-btrfs.rules
./rules/60-persistent-storage.rules
./rules/78-sound-card.rules
It has many other symptomps such as:
- Gui applications don't prompt elavated privileges to enter password.
For example when I click account type -> change button in
users-admin
window nothing happens ( gksu runs OK) - Nautilus doesn't mount partitions when I click them on the device list. I get "Not authorized to perform operation" error.
- Lightdm background image can not update according to user wallpaper.
- When I click nm-applet info section I get "No active connections found" error, though network connects automatically.
I can not reboot without root privileges which must reboot without
sudo
with following command :dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart
I get
org.freedesktop.ConsoleKit.Manager.NotPrivileged: Not Authorized error.
I like my desktop session, I don't want to reinstall whole system. Though it's uncomfortable to enter root privileges to run some applications, I can live with it if one of the smart guys doesn't find a solution.

I add /etc/pam.d/*
files. I thought sudo pam-auth-update --force
would fix the pam configuration but when I modify umask=0022
to umask=022
in /etc/pam.d/common-session
it did not notice the modification, and issued no warning.

Symptoms and proposed solutions are almost identical to this bug
one of the guys there claims that appending

session required pam_systemd.so
lines to /etc/pam.d/lightdm
fixes the bug. I tried it but it breaks lightdm, I even could not login with it.

Today when I saw udev and systemd updates in package I thought I was blessed thinking that update would fix the problem, but unfortunately nothing changed.
Here are the updated packages:
gir1.2-gudev-1.0 (1:204-5ubuntu20.17) to 1:204-5ubuntu20.18
libgudev-1.0-0 (1:204-5ubuntu20.17) to 1:204-5ubuntu20.18
libgudev-1.0-dev (1:204-5ubuntu20.17) to 1:204-5ubuntu20.18
libpam-systemd (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-daemon-dev (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-daemon0 (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-id128-0 (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-id128-dev (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-journal0 (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-login-dev (204-5ubuntu20.17) to 204-5ubuntu20.18
libsystemd-login0 (204-5ubuntu20.17) to 204-5ubuntu20.18
libudev-dev (204-5ubuntu20.17) to 204-5ubuntu20.18
libudev1 (204-5ubuntu20.17) to 204-5ubuntu20.18
python-systemd (204-5ubuntu20.17) to 204-5ubuntu20.18
systemd-services (204-5ubuntu20.17) to 204-5ubuntu20.18
udev (204-5ubuntu20.17) to 204-5ubuntu20.18
So, what might be the problem?
EDIT:5
Today I noticed that after the problem arose when I tried to set more permissive authorship I wrongly messed up the ownership in /etc/polkit-1/localauthority
I issued sudo chown -R 777 /etc/polkit-1
instead of sudo chmod -R 755 /etc/polkit-1
. I set it to sudo chown root:root -R /etc/polkit-1
today.
By the way I noticed that /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
is not that important. I even removed the package that contains it ( policykit-1-gnome ). I tested if it did any change, nothing changed. Then I removed consolekit
to see the function of it, when I removed it apt-get reinstalled policykit-1-gnome
, berevity of consolekit
has no effect on solving the authentication problem I have too.
I don't know if it's important, here is the pam-auth-update
list:
│ [*] Unix authentication
│ [*] Winbind NT/Active Directory authentication
│ [*] Mount volumes for user
│ [*] LDAP Authentication
│ [*] Register user sessions in the systemd control group hierarchy
│ [*] SMB password synchronization
│ [*] GNOME Keyring Daemon - Login keyring management
│ [*] ConsoleKit Session Management
│ [*] Inheritable Capabilities Management
EDIT:6
I am beginning to think that it has nothing to do with my modification to file system. I noticed that upstart job is not running. May it be related to upstart -> systemd transition of init process?
Because
echo $UPSTART_SESSION
and
initctl list-sessions
returns empty string.
I wonder how my system boots up?
policykit
: maybe installation of systemd removed or disabled some polkit components? What doesdpkg -l | grep 'pol.*kit'
say?ps -ef | grep [p]olkit
root 1839 1 0 14:42 ? 00:00:04 /usr/lib/policykit-1/polkitd --no-debug
