Trying to install pip with Ubuntu version 20.04, Python version 3.8 on my Oracle virtual box. Tried everything to install pip but failed
Steps tried
$ sudo apt update
$ sudo apt install python3-pip
Also tried
$ sudo apt-get install python3-pip
Error both times
python3-pip is not available but is being used by another candidate. This may mean that the package has been obsolete, has been missing or is only available from another source.
E: Package 'python3-pip' has no installation candidate
