I ran do-release-upgrade and before it started downloading pressed Ctrl+C. When I ran the command again it mentioned:

Please install all available updates for your release before upgrading.

I obliged (apt-get update, apt-get upgrade) but shortly after realized it was updating to Bionic. Here is the partial output of 

grep ^ /etc/apt/sources.list /etc/apt/sources.list.d/*

Some packages of the new release are installed now. If I run 

sudo apt update && sudo apt upgrade -f

I get 

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python-rna : Depends: libgsl2 but it is not installable
E: Broken packages

Help needed!

  • Were any packages got updated to that of Bionic? – Kulfy Feb 23 '20 at 15:44
  • Yes, like python3 is 3.6 now. That's the main problem. – Reza Feb 23 '20 at 15:47
  • Don't you want to upgrade to Bionic now? The upgrade can still be performed simply by `apt update && apt upgrade` since the sources.list now contains repositories of Bionic. This is known as [Brute force method](https://askubuntu.com/a/361490/816190). – Kulfy Feb 23 '20 at 15:49
  • I get: E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root? – Reza Feb 23 '20 at 15:54
  • You need sudo privileges to perform the action. Run `sudo apt update && sudo apt upgrade`. – Kulfy Feb 23 '20 at 15:55
  • Still error. I updated the question. – Reza Feb 23 '20 at 15:58
  • How did you install `python-rna` in the past? – Kulfy Feb 23 '20 at 16:01
  • From a ppa I believe. – Reza Feb 23 '20 at 16:03
  • Let us [continue this discussion in chat](https://chat.stackexchange.com/rooms/104815/discussion-between-kulfy-and-reza). – Kulfy Feb 23 '20 at 16:05
