I usually use /tmp when I download files that I need just this one time so that they're be deleted automatically. But snap chromium sees /tmp/snap.chromium/tmp as /tmp and for the worst of it, the user hasn't permission to open this directory. I know almost nothing of how snap works and am wondering if there is a way to grant /tmp access to some snap application?

    Does this answer your question? [Why can't Chromium suddenly access any partition except for /home?](https://askubuntu.com/questions/1184357/why-cant-chromium-suddenly-access-any-partition-except-for-home) – Dan Dascalescu Jun 17 '20 at 16:58
  • @DanDascalescu I can not find any snap plug for `/tmp` directory to connect to chromium snap. – Mehraban Jun 17 '20 at 19:26
  • You don't need any plug, that's the idea in that answer. Any path works. – Dan Dascalescu Jun 17 '20 at 20:11
  • @DanDascalescu Do you mean the workaround with unsnapped instance of chromium or `snap:connect` one? – Mehraban Jun 20 '20 at 12:19
  • Right, I meant to link to [my answer](https://askubuntu.com/questions/1184357/why-cant-chromium-suddenly-access-any-partition-except-for-home/1251289#1251289). I guess that could be called "unsnapped". – Dan Dascalescu Jun 22 '20 at 21:48

I also find this quite annoying. The solution offered here: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1851250 is to mount a tmpfs under your home directory.

There is more information here: Why can't Chromium suddenly access any partition except for /home?, along with some other solutions such as installing a non-snap package if you're interested.

    Can you described a little more the way how to solve this issue by explaining each steps? Please [edit](https://askubuntu.com/posts/1192185/edit) your answer – damadam Nov 28 '19 at 10:12
  • @damadam I think it would be best asked as a separate question. As a pointer, this answer helped me: https://unix.stackexchange.com/a/192458/179655. – Bernie Dec 01 '19 at 06:23
  • Add this link in [edit](https://askubuntu.com/posts/1192185/edit) instead of comment, I just say that in order to avoid your answer to be flagged as link-only answer (which aren't well-received in general) – damadam Dec 02 '19 at 08:16
  • @damadam It's not a link-only answer. I've included the solution, which is to mount a tmpfs under your home directory. If you're unsure how to do that I think it would be best asked as a separate question. – Bernie Dec 03 '19 at 06:26
  • Problem in your answer is that you just add links without explaining essentials interessant parts of these, which is not how AskUbuntu works; I just recommend you to improve your answer by extracting essential steps (that could be interesting for you, better is an answer, higher are chance to upvote it) – damadam Dec 03 '19 at 08:07
  • @damadam I thank you for your concern regarding my reputation, however, I believe I've included the essential information from the links I provided. I've edited my answer to include a solution from the other question that I linked to. Neither of them is ideal, but, IMO, the problem is really in the design of the snap system, and I don't have a feasible solution to that. – Bernie Dec 03 '19 at 10:47
  • @damadam as to explaining the steps I took in detail - other users have raised security concerns about the method I used. I'm not conversant enough about GNU to evaluate the pros and cons of the approach, so don't want to propagate a potentially dangerous solution. That's why I recommend that it be asked as a separate question. – Bernie Dec 03 '19 at 10:47
  • You can explain what you write in comment by editing your answer, it would be a good answer, even if it didn't solve totally OP issue – damadam Dec 03 '19 at 10:49
  • snap is awful... – Dave Ankin Sep 02 '20 at 22:57
  • This is the correct answer, at least for the time being. But the answer should not call this a “solution”. – Torsten Bronger Jan 28 '21 at 08:27

I've run into exactly that problem. It took me some time to understand what was going on as the path /tmp appears in the save as... window (instead of the real path /tmp/snap.chromium/tmp).

    I knew this but it doesn't help me access my files any easier. `/tmp/snap.chromium/tmp` needs extra permission to access besides when I click on downloaded files, associated programs does not prompt to open the file (this I don't know why). – Mehraban Nov 23 '19 at 12:14
