In the options, there are a few to check. Since I've erased the config files,
I rechecked them. No success though.
"gvfs-mount -d /dev/sdb1" tells me
"gvfs-mount: command not found".
After a bit of reading, I installed the missing gvfs-bin.
Now I have "Pas de volume pour le fichier de périphérique /dev/sdb1".
"udisksctl mount -b /dev/sdb1" prompts for the pass, and mounts the drive
just fine.
I'll try with Nautilus again.
That gvfs-mount looks promising (thanks btw). I have nothing in my ~/.gvfs
folder, even after that gvfs-mount command.
I need some rest, then I should also try this:
