> I did not changed my source repositories. Do I need to change something on it?
well you did at some point, ii libglib2.0-0:amd64 2.64.3-1~ubuntu20.04.1 amd64 GLib library of C routines that version isn't available in your sources, it comes from focal- updates, so either you enabled the updates repository to install it or did something else? the issue is that libglib2.0-dev need to be a matching version but you removed the source containing the version of glib you are based on, you either need to enable focal-updates or reinstall the focal version of libglib2.0-0 (apt install --reinstall libglib2.0-0/focal) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896405 Title: Cannot install libglib2.0-dev on ubuntu 20.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/1896405/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
