(Dist: Debian 10)
I have a reoccurring error message that mainly pops up when using systemctl (also when installing a package, and occasionally in a few other places that escape me),
Unit -.mount is masked.
Sometimes (depending on what command called the error message) it is more verbose, such as
Error: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit -.mount is masked.
This error doesn’t impede installing packages or any systemd services which are enabled already (and as such are loaded at boot), but using
service to restart, start or stop a service fails. This means I have to reboot the whole server to restart a service, which can be a little annoying.
Trying to unmask the root mount with
systemctl unmask -- -.mount appears to work (nothing is returned), but
systemctl status -- -.mount still outputs the following after:
● -.mount - Root Mount Loaded: masked (Reason: Unit -.mount is masked.) Active: active (mounted) since Mon 2019-08-05 15:03:38 AEST; 4h 8min ago Where: / What: /dev/sde1 Tasks: 0 (limit: 4915) Memory: 0B CGroup: /system.slice/-.mount
Any ideas? I’m don’t want to start from a fresh install for this server, so either I find a fix or just deal with having to restart if I need to reload a service.
