Hi,
First of all I don't know whether this post is posted in the right category. So, excuse me if its not.
I kind of screwed up my laptop today. Accidentally removed python!! During this process I realized thats its removing packages like evince, gstream etc...so I used force quit but the damage was done already.
Rebooting the computer initially complained that it is running on low graphics and tried various combinations which were listed but didn't work. Later on while I tried to boot it several times, it never reached the login screen.
I tried to reboot my computer in recovery mode. Tried to update the system from there. For example
sudo apt-get update
it spits these lines

My computer is behind the university proxy. None of the suggestions on google worked to solve this issue.
I am skeptical whether I can fix this without reinstalling.
Any suggestions will be of great help.
