Two of my small herd of Debian 10.2 (buster) machines are now giving me this error in the middle of running "apt upgrade":
Error: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit -.mount is masked. Other machines are not giving me that error. Partial output from this morning's run: Setting up git-doc (1:2.20.1-2+deb10u1) ... Setting up git-man (1:2.20.1-2+deb10u1) ... Setting up git (1:2.20.1-2+deb10u1) ... Processing triggers for man-db (2.8.5-2) ... Error: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit -.mount is masked. localepurge: Disk space freed in /usr/share/locale: 5332 KiB localepurge: Disk space freed in /usr/share/man: 0 KiB The upgrade seemed to go well otherwise. A bit of reading up on what "masking" means in systemd reveals that a "masked" unit is one that has a symlink to /dev/null in /etc/systemd/system. One of the offending boxes, hawk, has a slew of masked services, some of them (judging by the names) relate to mount. The other, iorich, has only one masked service, and that one has no relation I can discern to mount. So several questions: Why am I getting this error? Who or what masked a bunch or services on the one machine? And why? The symlinks are dated 7 August 2019. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
