I have been using Slack (Desktop App) for months now, without any problem. Today, for no apparent reason, the laptop (HP Envy) froze and since then Slack is not working anymore. It seems to try to launch, but then nothing. Any ideas?
Looks like there is a confirmed issue with the snap package.
We’re very sorry for the trouble there. We are experiencing some difficulties with the Slack Snap package. Our team is working hard to resolve the issue as quickly as possible. For now, you can access Slack via a browser or on our Direct Download version: https://slack.com/intl/en-gb/downloads/linux?eu_nc=1
A fix should be available in the next snap slack package release.
Slack 4.7.0 seems to be the issue. Contrary to one of the comments above, it is entirely possible to install an older version, which is one of the key features of Snaps...
To revert back to the previous version of Slack, use
sudo snap revert slack:
$ snap list --all slack Name Version Rev Tracking Publisher Notes slack 4.4.3 24 latest/stable slack✓ disabled,classic slack 4.7.0 25 latest/stable slack✓ classic $ sudo snap refresh slack snap "slack" has no updates available $ sudo snap revert slack slack reverted to 4.4.3
Try to update again when there is a version above 4.7.0. This resolved my issue on Ubuntu 18.04 which exhibited the same issue (try to launch then immediately closes).
I fixed this problem by removing the snap and installing the deb instead. https://slack.com/downloads/linux
Installing the latest version (4.7.0) directly through .deb worked for me on Ubuntu 20.04:
wget https://downloads.slack-edge.com/linux_releases/slack-desktop-4.7.0-amd64.deb sudo dpkg -i slack-desktop-4.7.0-amd64.deb rm slack-desktop-4.7.0-amd64.deb
I would prefer to install through Snap so I'm going to keep an update on the Snapcraft release to see when it hits the next version. Until then, this is a good work-around.
