I have installed the latest Slack 3.3.3 from the official website. Downloaded the deb package, but when i start it, it simply crash and nothing happens. It was working fine on Ubuntu 18.04. Is there a way to debug why this app its not working? Thanks!

Link where i downloaded slack from

When trying to run slack with sudo snap run slack i am getting those errors

mkdir: cannot create directory '/run/user/0': Permission denied No protocol specified

(spotify:5309): Gtk-WARNING **: cannot open display: :0

and when i run it without sudo my whole system crash and restarts by itself.

UPDATE I wrote to slack and this is what they have answered me

Thanks for getting in touch, and I'm sorry for the troubles with Slack on Ubuntu 18.10.

We're aware of the issue, and we're already working on a solution. We're confident that we'll be able to put out a version update with a fix very soon. Sorry for the inconvenience here.

Same here after update Ubuntu from 18.04 to 18.10 yesterday.

Slack v3.3.1 stopped working. Tried update to v3.3.3 with no luck. Both Official Slack deb versions.

Trying run Slack from terminal, just prints Segmentation fault (core dumped). Based on this, Slack came back to work:

sudo mv /usr/lib/slack/libnode.so /usr/lib/slack/libnode.so.bad
sudo ln -s /usr/share/atom/libnode.so /usr/lib/slack/libnode.so

Basically, glibc 2.28 causes a segfault (Fedora 29 and other latest/beta distros are affected for the most part). It should be fixed in the next release.

In the meantime, switch to slack 3.1.1 or downgrade glibc to 2.27-3.
