i think that udisks is running. In the command line i've:
Code:
ribez@ribez-VPCEB1M1E ~ $ udisksctl mount -b /dev/sdb
Mounted /dev/sdb at /media/ribez/KOBOeReader.
Could the problem be that i've installed Calibre via Flathub?
Unfortunaly the Linux Mint package manager installs an old version of calibre (2.55) so i've installed a flatpak version
