I'm a newbie in using ubuntu. Yesterday I was installing a few packages. During the process, at certain point the sudo command did not work anymore. So I rebooted, and it just stuck at booting page. I tried to search solutions online, got into recovery mode, tried a few things. Nothing works. Now when I reboot, I get error messages saying "Failed to sart Network Manager. Failed to start login servcice. "

I don't want to reinstall the system. What can I do now?

Any help would be greatly appreciated! Thanks!

Thanks for trying to help! I don't remember exactly what was prompted at first. When I went to recovery mode, using sudo command gave: sudo: unable to stat /etc/sudoers: Permission denied sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin

I have no idea of what going on. But I did find a solution from a youtube clip. Basically, it's running a few commands as follows. /sbin/fsck -fy /sbin/mount -wu / /bin/chmod 1775 / /bin/sync exit

Some of them didn't work. Some worked. At the end, I can log back in again without knowing what happened...
