Ubuntu 16.04 Nvidia 361.42 black screen + cannot remove /var/lib/dpkg/lock: Read-only

Hi,

there are some Q&A about this in the internet, but I haven't been able to solve the problem so far, maybe cause I'm new to Linux.

I had problems with update / upgrade which always got stuck on the same line:



Yesterday after switching my lap on I got a login page and then black screen with cursor.
I tried different solutions, but nothing worked. I have a Win10/Ubuntu dual boot, so I switched to Ubuntu advanced options and chose 'root - root to shell prompt' and tried some commands. Every time I get the same problem:

sudo rm /var/lib/dpkg/lock

didn't work, I got:

cannot remove /var/lib/dpkg/lock: Read-only file

Please help - I can't work without Ubuntu and I have many files there :/

cannot remove /var/lib/dpkg/lock: Read-only file

Once in the recovery shell try..

sudo mount -o remount,rw /

Then try your commands again.

Please also try..

sudo rm -rf /var/lib/dpkg/lock
sudo dpkg --configure -a

thanks.

Omg thank you very much, after running commands you suggested my Ubuntu is alive again )))) Yeah!!!! I'm writing from Ubuntu now )
But I don't know what do to next. I mean I don't want to get into such problem again. What to do with Nvidia? I'm afraid of update and upgrade now.

Hi, it should be ok now to run the commands, just do not do it with a root prompt #root
Bring up a regular terminal with keypress "ctrl/alt/t" then do..

sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoremove
 sudo apt-get autoclean

Thanks.
