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:
 mysql-workbench : Depends: gdal-abi-2-2-3
                   Depends: libgdal20 (>= 2.0.1) but it is not going to be installed

These commands gave no output

dpkg --get-selections | grep hold`
sudo dpkg --configure -a
apt-mark showhold 

I also tried using aptitude instead of apt. I used synaptic package manager. Edit -> Fix Broken Packages. It shows "Successfully fixed dependency problems" at the bottom but problem still not solved.

Edit: I ran this command

apt-cache policy mysql-workbench

Output

mysql-workbench:
  Installed: (none)
  Candidate: 6.3.8+dfsg-1build3
  Version table:

Edit2: I ran this command

apt-cache policy gdal-abi-2-2-3 libgdal20

Output

gdal-abi-2-2-3:
  Installed: (none)
  Candidate: (none)
  Version table:
libgdal20:

Edit3 I ran this command

sudo apt install libgdal20

E: Unable to correct problems, you have held broken packages.

If I try to install any of the dependencies, the same error shows up again telling their dependencies. But isn't apt supposed to install all the dependencies on its own?

Edit 4: I ran this command

gedit /etc/apt/sources.list

Output https://paste.ubuntu.com/p/VncCrpPNHY/

Edit 5 I tried installing it with synaptic package manager. On clicking apply after marking mysql-workbench for installation, I got a dialogue box that says

Could not apply changes. Fix broken packages first.

On going to Edit -> Fix Broken Packages, I get a dialogue box that says

E: Unable to correct problems, you have held broken packages.
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies

However if I just open synaptic and do Edit -> fix broken packages without marking MySQL workbench for installation, it says at the bottom "successfully fixed dependency problems".

I ran

sudo apt update
