It looks like a previous install of ttf-mscorefonts-installer failed. But reinstalling it may fail because of bug 1607535, since your version of apt is apparently < 1.2.19. Try removing it completely, updating apt packages to 1.2.19, and reinstalling it:
sudo apt-get purge ttf-mscorefonts-installer sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ttf-mscorefonts-installer If you don't want to upgrade your whole system, use "install apt- transport-https" instead of "dist-upgrade" to upgrade only specific packages. The fix is in apt-transport-https, but you may want to upgrade all upgradeable APT packages for consistency: you can find them with "apt list --upgradable apt\*". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660556 Title: package ttf-mscorefonts-installer 3.4+nmu1ubuntu2 failed to install/upgrade: Paket ttf-mscorefonts-installer ist nicht bereit zur Konfiguration kann nicht konfiguriert werden (momentaner Status »half-installed«) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/msttcorefonts/+bug/1660556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
