open file on network using bookmark for Keepass2

Solution 1:

I had the same problem on Ubuntu 20.04 In my experience KeePass2 isn't a good keepass client for Ubuntu. Instead go for KeePassXC which also has a nice plugin for the browser and a couple of android apps.

What works for me is saving my "vault.kdbx" file in a cloud storage. To access my vault on my mobile devices I use FolderSync to sync the file 2-way each 15 minutes (you can choose the time yourself)

Another solution is using an ftp-synchroniser to sync the "vault.kdbx" to your file system. This way KeePassXC (or KeePass2) kan open a file that resides in a "not-mounted-folder"
