I have never used Cryptomator. I just installed ver 1.4.6 on Ubuntu 18.04 via PPA, I open the app and see the gui as expected. I left all settings as default. I tried to add a vault and a window opened at “/tmp/.mount_cryptoSCizMq/app/” with a list of jar files. I was expecting a different setup window. Am I missing something. I rebooted and got the same thing.
Update: So I uninstalled 1.4.6 and installed 1.3.2 via deb. Same results. I get the following screen when trying to create a new vault:
Starting with 1.4.x, Cryptomator is distributed as an Appimage, which means the application is not “installed” to normal directories but rather get’s mounted to /tmp when executing. What you’re seeing here is the mounted application directory.
You shouldn’t end up here (thanks for telling us, we need to fix this 
), instead you’re supposed to choose a storage location for your vault somewhere more “normal”, e.g. ~/someCloudDir/vaultXYZ.
On the top left of your file picker dialog, you can navigate to your file system root and then you should be able to go to your home directory.
I tried again and successfully created a vault in my home directory on my PC. But I was thinking I could configure my drop box or some other online storage when creating vault. So it appears I would need to install the dropbox desktop app, mount the dropbox drive and create the vault there. Is that correct?
Im not sure, but doesn’t the Dropbox client just sync? I was not aware of that it does also provide a mounted drive.
But in general:
Yes, that is how Cryptomator is designed.
You create the vault local at a place that is synced with eg a Dropbox client or gdrive client to you online storage.
The client then syncs the encrypted files to your online storage.
