Back In Time

Cannot launch Back-in-Time (root) after System Restart

Asked by Harry Wells

I had to reboot my system (Ubuntu 12.04) because BiT (root) was stuck restoring /proc directory. The system rebooted fine but when i tried to launch BiT (root) from the icon nothing happens.

I also tried to launch from command line using 'gksu back-in-time' but again nothing happens. On the other hand the non-root version of BiT works fine.

Thank you in advance

First of all please don't ever try to restore /proc /sys /dev or /run. These are internal folders from Linux kernel which will be recreated if they are not present at boot. They are excluded by default in BIT for a good reason.

To get back to BIT (root) you could try to remove (or rename) '/root/.local/share/backintime'. If that doesn't help remove '/root/.config/backintime/config' as well. In that case you will have to recreate your configuration again, too.

It seems that because i restored wrongly my system, the restore messed up permissions of /usr/bin/sudo. I was not able to 'su' and i was getting the message sudo: must be setuid root

I had to reboot my system to recovery mode and issue the following commands in order to fix things :

mount -o remount,rw /

mount --all

chown root:root /usr/bin/sudo

chmod 4755 /usr/bin/sudo

restart
