I am upgrading my 14.04LTS Ubuntu to 16.04. The problem is that it's been at the same step (Configuring openssl amd64) for like 20 hours. I tried to get to the terminal to know what is happening but the terminal just doesn't open. In Xterm I ran a few commands to resume the installation since Possibly my laptop lost connection and typed in XTerm:
$ sudo apt-get install -f
which displays Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-fronted), is an other process using it?
Which is understandable for the somewhat frozen upgrading process.
Then I typed:
sudo screen -D -r
But the screen: is not found
Sutting down my laptop is not an option here since I do not want to ducplicate packages. Also, installing a virtual machine to run something remote I am not sure how to do it.
Can this be fixed from the XTerm?
Thanks in advance and looking forward to your replies.
