Hi, sorry for my late reply too! Thanks for all the feedback. You hit the spot this time :-)
== My group ID for "systemd-networkd" was wrong ! == I found out that my /etc/group was all messed up. I have no idea where this came from (I kept bringing these files over during upgrades and migrations and never compared my /etc/group with a fresh install) Thank you for your time and help - I see the problem solved! BTW: netplan.io 1.0.1 - (of course) has the same behavior, didn't work with wrong group ID But it works now, too -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2074266 Title: 24.04: latest netplan updates fail to apply already working config To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/2074266/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
