after updating Kubuntu from 20 to 22, Firefox has been forcefully installed from snap. After that, I cannot download and save any file at any place, not only in home directory. I've given all explicit permissions to Firefox in the Kubuntu's software manager (Discover) with no effect. Also, I have a similar problems in other apps installed from snap. What else can I try to do to give all permissions to those apps?

UPD1. The previous Kubuntu version was 20.04.4. I updated to 22.04.

UPD2. Output for snap connections firefox

  • https://askubuntu.com/a/1285102/289138 - then google for a ppa / deb on firefox, it is out there – Hannu May 01 '22 at 16:14
  • If you upgraded a Ubuntu Core 20 system to 22; no user application will be changed which is one of the benefits of the year based products (20 & 22). On the 20.04 to 22.04 or year.month products all non-snap applications get changed. 20 & 20.04 are different Ubuntu products. Snap packages run confined which has security benefits, but those security benefits incur limitations; some directories can be enabled (snap connect) where as others cannot. You've not specified. Please be precise with details (20 != 20.04 & 22 != 22.04) – guiverc May 01 '22 at 22:20
  • If you cannot save files in your home directory, that's a bug -- please report it to the Mozilla bug tracker with enough detail for a developer to reproduce the issue. If you are regularly saving files outside your home directory, that is usage that the Mozilla developers did not foresee -- we will need more details to know if using snaps that way can be enabled. – user535733 May 01 '22 at 23:00
  • Thanks for the comments, I've added some info to the post. – Artem Plyusnin May 02 '22 at 06:29
  • I agree with @user535733 This is likely buggy behavior, possible at the level of xdg-portal. Select a folder in your home directory, you cannot save. Make a new one: you can save there, select the previous folder on the path bar - now you can save. If that is not buggy, then the logic of the design is not clear to me. – vanadium May 02 '22 at 06:47
  • Does this answer your question? How to install Firefox as a traditional deb package (without snap) in Ubuntu 22.04 (jammy) – Archisman Panigrahi May 02 '22 at 07:13

    @ArchismanPanigrahi While it is fine to refer to that answer for providing the option to move to deb, it is intellectually unfair marking this as a duplicate and avoid any answer to the current question about the snap version that comes by default with the distribution. – vanadium May 02 '22 at 07:25

    Does this answer your question? accessing files outside of /home in snap apps – karel May 02 '22 at 07:43
  • @karel thanks, as I added previously in the post, all necessary connections are established (at least it looks so). I've reported a bug on bugzilla – Artem Plyusnin May 03 '22 at 13:07
  • @ArtemPlyusnin I'm sorry for being dumb. I was just being careful that you enabled connections to removable devices. – karel May 03 '22 at 13:11
