I had a similar problem when using the nm-connection-editor. It seems to me that it does not save a manual system configuration because the directory where the configuration should be stored is missing.
After creating the /etc/NetworkManager/system-connections/ directory, I was able to save the manual configuration and it is also automatically used when I restart the computer. -- Manual configuration don't work https://bugs.launchpad.net/bugs/251763 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
