Mounting filesystem. To unmount, call:
$ cryfs-unmount "/home/xxx/Documents/pcloud-clear"

then

cryfs-unmount /home/xxx/Documents/pcloud-clear

Unmounting CryFS filesystem at "/home/rgallet/Documents/pcloud-clear".
Error: Could not unmount filesystem

I tried with a new directory and mount point. Also tried with compiled-from-source cryfs. Same results.

I'm running arch linux. The commands I issue have no changed. But obviously Arch is a rolling distro, so something there must have broken it. Yet it is not something cryfs seems to notice.

I experienced similar issue. Try running it in foreground mode (-f), in my case the problem was:

[2022-10-08 15:28:18.794] [cryfs] [error] Crashed: locale::facet::_S_create_c_locale name not valid

Regenerating locales with locale-gen solved the problem.

It's suboptimal that cryfs silences those error in background mode, but knowing about foreground makes things easier.
