- Open the Network List (Ctrl + S)
- If the Libera.Chat network exists in the list, then click on Edit and skip ahead to step 5
- If it does not yet exist in the list, click Add and type Libera.Chat, then hit enter and click on Edit
- Replace the string
newserver/6667 with irc.libera.chat/6667
- In the User name field, enter your primary nick Select
SASL (username + password) for the Login method field
- In the Password field, enter your NickServ password
If you are unable to edit the User name field, the change can be made
in the User Information section on the Network List window.
If everything was configured correctly, you should see a SASL
authentication successful message when you connect. You will already
be identified to NickServ, so you don’t need to do this again.
Note: on my Lubuntu impish system I could not skip from step 2 to 5; but that could be because my system is old (many-many-release-upgrades)
