This has been going on for at least 6 years now! Even though I am not a Ubuntu man (for historical reasons I am on OpenSuse), it is highly relevant to me, because after the latest OS upgrade, my time-honoured Acrobat Reader 9 (Linux version!) can finally not run any more. So I installed the snap "acrordrdc", which runs a more modern version of the Reader.
But, the restrictions discussed here leave an Acrobat Reader under snapd almost entirely useless: when trying to open a PDF file from inside a browser (e.g. Firefox) or a mail program (e.g. Thunderbird), that application will download the file into the /tmp hierarchy and then call the default application for .pdf with that path as an argument. Which, of course, won't work if I set my snap-based Reader as the default! And loop-back mounting /tmp somewhere in the home directory does not help either, because the pathname passed on to the Reader will still start with /tmp. I am now working on a work-around wrapper, but that will be a kludge, not a solution. The whole issue also raises the silly question: what is so security- sensitive about /tmp? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643706 Title: snap apps need to be able to browse outside of user $HOME dir. for Desktop installs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1643706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
