Thanks for filing this bug in Ubuntu. I believe you used an older version of the new installer, which had a known bug where the universe component was not enabled in /etc/apt/sources.list:
https://bugs.launchpad.net/subiquity/+bug/1783129 Please check your sources.list and enable universe (and multiverse if you want), then you will find the krb5-user package. -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to krb5 in Ubuntu. https://bugs.launchpad.net/bugs/1840905 Title: krb5-user seems not installing on Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1840905/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
