Got response from Slack support that their engineers are aware of the issue and is currently investigating it
note that if it happened after an upgrade of slack (i.e. if it is a bug in the latest slack) you can always do
snap revert slack to go back to the former version you had installed … this is usually helpful if such a bug gets introduced with an upgrade …
Thanks. Good to know
I tried reverting to 4.18 but I still have the same crashing problem.
Same here. Any updates, anyone?
Remove and re install it again fixed the issue.
sudo snap remove slack
sudo snap install slack - - classic (remove space between dash)
can confirm here as well, reinstalling it works:
slack 4.19.2 from Slack✓ installed
Any updates on this?
Reinstalling did not work for me.
Removing the snap version and installing .deb worked for me: https://slack.com/intl/en-pl/downloads/linux
I also had this issue. Due to another immediate issue (Slack crashes on upload), I deleted the cache directory (
~/snap/slack/common/.cache) and this actually resolved this particular crash issue as well.
Thanks for this tip! removing ~/snap/slack/common/.cache resolves the following crashes
- lock screen
upload from computer
- uploading a profile pic
- adding an emoji
- attaching a file to the report issue
unfortunately a revert has the bug where it didn’t previously. Clearing the cache as Nikarmotte suggested does stop my app from crashing
Works for me
This worked for me too. Interestingly, using ‘Help/Troubleshooting/Clear Cache and Restart’ did not work for me (I tried that before). Also, instead of removing the cache dir, I put it to the side and then did a diff between the old one and the newly generated one and I found some things in the old one where it was pointing to things in the previous snap revision (which I had installed). I suspect there is a bug in the cache generation code and they need to point to the
current symlink rather than

Perhaps @hanskr (or someone else) would want to forward this along to Slack?
Your report (as well as some others) went a long way to tracking this down. Thanks for the assist!
I forwarded this to the help ticket I had.
Thank you guys. This fix worked for me as well
I’m on ubuntu 21.04, I don’t know if slack updated recently on my pc, the fact is that I often reduce it in the tray bar, and after some time (around 1h) the app is not running anymore.
It just stops without giving any alert, so I’m guessing that there may be an issue similar to the one reported here.
In fact I read about file upload problems, solved by clearing the cache (it happened to me as well a couple of times).
I’ll try this solution to see if works, otherwise I’ll try to do a fresh install. In case that someone is interested, I’ll post the result once I know
I can confirm what @jdstrand said:
- using the GUI menus to clean the cache does not work, however
- removing the cache directory directly does:
rm -rf ~/snap/slack/common/.cache
Thanks for the tip. This did not work for me either, but this is good to know.
