I'm using Ubuntu 12.04. By accident I deleted /etc/profile.d/bash_completion.sh. I then restored it by copying that same file from another similar Linux machine (same OS).

Now I can't login because the login screen keeps coming back after each successful login. I tried both Xubunto session and Xfce.

Any suggestions will be greatly appreciated.

  • Please edit your question and include i) the output of ls -l /etc/profile.d/bash_completion.sh and ii) the contents of your ~/.xsession-errors file. You can use a live CD to get these if needed.

If you think it's that file that's responsible, you could reset it back to the packaged defaults by reinstalling the bash-completion package. We have to be a little more forceful to get it to copy the configuration back, but this should work:

sudo rm /etc/profile.d/bash_completion.sh
sudo apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall bash-completion

Reboot and see where that gets you.


It has just struck me that you might have problems getting to a terminal to enter this! There are several options there but here are my favourite:

They should both set you up as root on your install, and from there you should be able to action a change. If nothing else just delete the current bash_completion.sh file. That should allow you to log back in normally, albeit without Bash autocompletes.

I've tried a lot of different things including removing that file but it didn't work.

Finally I solved my problem by deleting the .dmrc file in my home directory. I accessed tty1 console (Ctrl+Alt+F1) and did it from there.

Thank you.
