Files doesn't prompt cryptsetup-bin install when needed

[Ads20000]

When attempting to unlock an encrypted drive without cryptsetup-bin installed, Files errors out. Files should bring up a prompt to install cryptsetup-bin in the relevant package manager (in our case, Apt) when one attempts to unlock an encrypted drive. I.e., I plug in the encrypted drive, Files tells me that cryptsetup-bin needs to be installed and prompts the relevant package manager GUI (can't remember what this is in Ubuntu when it isn't full-blown Ubuntu Software) to give me a dialogue box and a button to press to install it, I enter my password, it is installed.

For an example of how this could work, see what happens when, on a clean install, you try to do a backup with the Backups program.
