There are two choices here:
- Use the AppImage 1.4.0 Beta 1 from here which uses FUSE (use at your own risk):
- Install version 1.3.2 from the 16.04 deb and manually mount the vault using DAVFS. To do this, open the vault as normal, then create a directory (for example, mine is /home/$USER/Cryptomator) and mount it with the following command:
sudo mount -t davfs -o gid=<INSERT USER ID HERE>,uid=<INSERT USER ID HERE> http://localhost:<INSERT PORT HERE>/<INSERT PREFIX HERE>/<INSERT VAULT NAME HERE>/ /home/$USER/Cryptomator
So for example, mine looks like this:
sudo mount -t davfs -o gid=chris,uid=chris http://localhost:42427/alPso2vyRLJy/Documents/ /home/chris/Cryptomator
You don’t have to specify a Username or Password when it asks.
Then open and modify files from the /home/$USER/Cryptomator folder (or whatever mount point you choose).
When you are done with the vault, first pass this command:
sudo umount /home/$USER/Cryptomator
Then there is a bug in 18.04 which means you have to first eject the vault in your file manager (PCManFM here) before locking the vault in Cryptomator.
I’ve been using the second method in Xubuntu 18.04 since it was released and it seems to be OK.
