[Touch-packages] [Bug 1913979] Re: misleading error messages when /etc/NetworkManager/system-connections is a cross-filesystem symlink
I think there are multiple bugs in play here. My system-connections dir is a symlink within the same filesystem, and whenever I try to save a new connection I get the "settings plugin does not support adding connections" message.

[Touch-packages] [Bug 1913979] Re: misleading error messages when /etc/NetworkManager/system-connections is a cross-filesystem symlink
I see this behaviour also when /etc is still on the rootfs, but fstab has a "ro" for rootfs. on Ubuntu 18.04 LTS and 20.04 LTS (arm versions for odroids, but not unlikely generally), I get a # nmcli con add type ethernet ifname eth0 con-name X "Error: Failed to add 'X' connection: failure adding connection: settings plugin does not support adding connections" Changing fstab to rw and rebooting removes the error; added or modified connections, including static ip addresses, Wifi connections etc, will persist and work as expected when rebooting later with ro for rootfs in fstab. for me, any fix would ideally enable functionality after a simple # mount -o remount,rw /dev/mmcblk0p2 / instead of having to change fstab and reboot. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1913979 Title: misleading error messages when /etc/NetworkManager/system-connections is a cross-filesystem symlink Status in network-manager package in Ubuntu: New Bug description: If the /etc/NetworkManager/system-connections directory is a cross- filesystem symlink, activating connections will fail with the unrelated messages: * "failed to create file ...: Read-only file system" (TRACE level) * "failure adding connection: settings plugin does not support adding connections" (DEBUG level and above) * no error message (Gnome UI) I suspect moving the systems-connections directory onto a separate filesystem is not supported because network manager tries to atomically move a connection temp file into place and fails, but this is really hard to figure out since the error messages are completely unrelated.
