permissions after upgrade to ubuntu 22

tv flag

I cannot save data from firefox (or another browser) to a folder for which I have write permissions, like folders inside my home, but I can save to home! As far as I can see I have the correct permissions but Firefox keeps saying I don't. chromium tells me the same. This happened after the upgrade from 20 to 22.

You're asking about a Ubuntu Core 20 to Ubuntu Core 22 upgrade? or 20.04 to 22.04? Kubuntu doesn't support the *year* products (ie. 20 & 22)

Your details are vague, you mention `firefox` which is now a *snap* package, and also another *unstated* browser which makes me think of `chromium` now also *snap* packages. Those apps are now *confined* due to *snap* package which prevents them accessing the root file-system, but can access $HOME unless it's a symlink etc to another file-system, but you gave no specifics. I'll provide https://askubuntu.com/questions/1184357/why-cant-chromium-suddenly-access-any-partition-except-for-home/1184374#1184374 which may provide more details, but being specific can help us to help you.

Firefox and Chromium in Ubuntu 22.04 and newer releases come as Snaps.

Snap packages can currently access your /home directory and (almost) nowhere else. The applications simply cannot access most of your filesystem. It's a feature of snap confinement (sandboxing). Researchers keep discovering vulnerabilities in browser software, so that confinement seems like a desirable feature for most users.

But that feature does, unfortunately, break access to outside-home directories.

You have options:

  • You can modify your workflow: You can link to /home. Or you can sync to /home. The browsers cannot follow the link, but perhaps your other applications can. Or you can auto-sync between the locations.

  • You can use a deb or upstream binary instead of the snap. They are still available.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
