Package default-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

When i do sudo apt-get upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 minecraft-launcher : Depends: default-jre but it is not installable
 multimc : Depends: qt5-default but it is not installable
           Recommends: openjdk-8-jre but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

When i do sudo apt --fix-broken install i get

  • You cannot find them because you have no Ubuntu repositories listed in your sources. Just PPAs and third parties. See How do I restore the default repositories? – user535733 Feb 17 '21 at 20:09
  • Gentle reminder: Ubuntu 16.04 (Xenial) reaches the end of Community Support in April 2021. After that, we won't answer questions about it anymore. – user535733 Feb 17 '21 at 20:12
  • You have added the webupd8team ppa for java. It is empty. There are zero java packages in it. You should remove it. This has been the case for nearly two years. https://launchpad.net/~webupd8team/+archive/ubuntu/java – popey Feb 17 '21 at 20:12
  • Thank You for the suggestions, lemme do everything yall have suggested. Also, im using Ubuntu 18.04 LTS Xenial – reizu Feb 17 '21 at 23:30
