I cannot perform any upgrade using apt as there is some dependency issue with python3 on Ubuntu 18.04.

You might want to run 'apt --fix-broken install' to correct these.

The following packages have unmet dependencies:

 python3 : PreDepends: python3-minimal (= 3.6.5-3ubuntu1) but 3.6.7-1~18.04 is installed

 python3-dev : Depends: python3 (= 3.6.7-1~18.04) but 3.6.5-3ubuntu1 is installed

               Depends: libpython3-dev (= 3.6.7-1~18.04) but 3.6.5-3ubuntu1 is installed

 python3-distutils : Depends: python3 (>= 3.6.6-1~) but 3.6.5-3ubuntu1 is installed

 python3-lib2to3 : Depends: python3 (>= 3.6.6-1~) but 3.6.5-3ubuntu1 is installed

 python3-venv : Depends: python3 (= 3.6.7-1~18.04) but 3.6.5-3ubuntu1 is installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I tried apt-get install -f but did not solve the problem.

The following packages were automatically installed and are no longer required:

  libkeybinder-3.0-0 libregexp-common-perl pastebinit

Use 'sudo apt autoremove' to remove them.

The following additional packages will be installed:

  libpython3-dev libpython3-stdlib python3

Suggested packages:

  python3-doc

The following packages will be upgraded:

  libpython3-dev libpython3-stdlib python3
