In the new version of Ubuntu we will have something similar to flatseal?, getting permission to read snaps to secondary HD/SSD would be very useful and easy for new users this functionality as many new users who migrate from windows like me do not have as much technical knowledge to allow and use the terminal to use secondary SSDs in snaps, and thank you very much for creating the snaps they are very good
When Ubuntu 24.10 was released it came with an application called Security Center. It gave the user control over something called Permissions Prompting. It was experimental in Ubuntu 24.10. The Security Center is in Ubuntu 26.04 LTS - still under development.
I have just tested it using the snap version of Firefox. A dialog box appeared that allowed me to give Firefox access to folders in the /Home folder. Actually, Firefox wanted to access the camera. I set it to do so until the session was ended.
I am hoping that it may be possible to have a snap packaged application such as a music application access music files on another partition.
Here is the original announcement about Security Center and Permissions Prompting and the future intentions.
