ssh: Could not resolve hostname slack-master: Name or service not known

[Juan Manuel García]

Running ubuntu 14.04 LTS. with slack version 0.15.2 I get the following stack trace on a terminal when I try to start the program.

ssh: Could not resolve hostname slack-master: Name or service not known
rsync: did not see server greeting
rsync error: error starting client-server protocol (code 5) at main.c(1653) [Receiver=3.1.0]

Status changed to 'Confirmed' because the bug affects multiple users.

Any solution for that?

Initially I was trying to install 2.0.5th.deb version on ubuntu 14.04 but it was conflicting with exiting packeges and conf files to owerwrite.then I did
# sudo dpkg -i --force-overwrite slack-desktop-2.0.5-i386.deb
  Which gave slack icon in ubuntu-applications,but unable to run with producing above error.
  I replaced slack deb version with older one
# sudo dpkg -i slack-desktop-1.2.6-amd64.deb. (It was available on my server)

  It is working fine now ... :)

I got the same issue on environment where default user shell was 'fish'. If the 'slack' command is executed from bash shell it works fine.

remove the slack from the sbin: #sudo rm /usr/sbin/slack
now create a soft link: #sudo ln -s /usr/lib/slack/slack /usr/sbin/slack

This resolved the issue in my case. Now you can run slack from the terminal.

Puneet solution also worked for me

This can be fixed by downloading Slack from https://linuxize.com/post/how-to-install-slack-on-ubuntu-18-04/#1-download-slack.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we would
be grateful if you would provide a more complete description of the problem
with steps to reproduce, explain why you believe this is a bug in Ubuntu
rather than a problem specific to your system, and then change the bug
status back to "New".

[Expired for slack (Ubuntu) because there has been no activity for 60 days.]

Hello,

this issue is still exists, native slack deb archive contains broken version of the slack application and probably should be replaced with slack-desktop or renamed to slack-server.

The issue still exists on 22.04.3, even when installing via `snap`.

The workaround listed in https://bugs.launchpad.net/ubuntu/+source/slack/+bug/1386372/comments/5 still works.
