You're using the stock Ubuntu LTSP version. A systemd or network-manager update probably broke it. I don't think it's a bug in systemd or network-manager; but that update triggered a bug in LTSP that wasn't triggered previously.
I don't know of anyone maintaining the stock Ubuntu LTSP version. I'm an LTSP developer and I maintain newer versions of LTSP for Ubuntu in this PPA: https://launchpad.net/~ts.sch.gr/+archive/ubuntu/ppa If you add that PPA in your sources, both in the server and the chroot, and fully update, the problem you saw will probably go away. I do mention adding the PPA in the recommended LTSP installation instructions: http://wiki.ltsp.org/wiki/Installation/Ubuntu If someone wants to backport a newer LTSP version into stock Ubuntu repositories, he should follow the documentation at https://wiki.ubuntu.com/UbuntuBackports. Due to lack of time I'm not going to do it, but I'm willing to help anyone that is interested in continuously backporting newer LTSP versions into LTS Ubuntu versions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797839 Title: Ubuntu 18.04 LTS - ltsp clients lost network connection after tftp boot and network service start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/1797839/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
