dedlock: > I've been testing 3.9. veracrypt feature. I can open a normal veracrypt volume, but I couldn't to open a hidden one. I tried by checking the "hidden volume" and without it, with primary pass and with secondary pass (hidden volume password) with no luck. There is no way to open a hidden veracrypt volume.
It's a known issue that in the 3.9 release candidate, hidden volumes
cannot be unlocked via "Unlock VeraCrypt Volumes" or the file manager -
this will be fixed in 3.9.
But it should be possible to unlock hidden volumes via GNOME Disks.
Could you try that?
