It's not ".mount". It's "-.mount". Specifically, it's a systemd.mount(5) unit created to represent the root (/) file system. The / is converted to a - in the unit name. > I looked on the web and found a discussion involving something called > "zynthian." My log repeats the sentence several times -- from syslog and > daemon. I see this error reported on a pretty regular basis, but there isn't a single cause for it. I've heard of *several* different possible sources. > It happens only when I 'apt update' That rings a bell, but I don't remember the precise details. Are you a synaptic user, by chance? It might be a synaptic thing, either because synaptic is currently running, or because it broke something. Or... it could be something entirely different. I believe I've also heard of this problem being triggered by gparted. Have you used gparted in the last few days? If you can't find an answer with Google, try the standard troubleshooting steps. Read the logs, check the status of everything, etc. systemctl status -- -.mount would be a good starting point. Mine says: unicorn:~$ systemctl status -- -.mount ● -.mount - Root Mount Loaded: loaded (/etc/fstab; generated) Active: active (mounted) since Fri 2022-02-04 07:12:29 EST; 2 weeks 0 days> Where: / What: /dev/sda7 Docs: man:fstab(5) man:systemd-fstab-generator(8) Warning: some journal files were not opened due to insufficient permissions. Of course, running it as root would give additional details.
