I installed the snap version of Mailspring (using Snaptastic), but during install the .desktop file for some reason wasn't copied to /usr/share/applications/ or ~/.local/share/applications/ . I did that manually (to both locations) and now the icon is working and it's appearing in the Applications launcher, yet when I go to System Settings -> Applications, Mailspring isn't listed as an option under "Email Client". How can I fix this so that mailto: links go to Mailspring instead of Pantheon Mail?

When I tried the .deb version this worked flawlessly.

Mailspring option missing from Email Client menu

Mailspring appears in applications launcher

Here's the contents of the .desktop file:

[Desktop Entry]
Comment=The best email app for people and teams at work
Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/mailspring_mailspring.desktop /snap/bin/mailspring %U

  • What's the content of the desktop file you added? Does it include MimeType=x-scheme-handler/mailto;x-scheme-handler/mailspring;?

  • I've updated the question with the contents of the .desktop. Yes, it does indeed include that line.

After making changes to desktop files manually, you often have to run:

sudo update-desktop-database

This can also be pointed at your local user's desktop database like so:

update-desktop-database ~/.local/share/applications

And changes to mime types often need the following:

sudo update-mime-database /usr/share/mime

Although the update-mime-database command is not likely necessary in this case, as that's usually needed when new mime types are registered rather than adding new applications to existing mimes.
