[member=7763]Nikolay[/member]  I would start by removing the PPA  http://ppa.launchpad.net/audacity-team/daily  - looks like it may be the issue


This can be unchecked from "Software and Updates" under the "Other Software" tab..
Then try running updates again..
You can update from terminal or from Menu > Favorites > Install Updates


Also within the manual
https://www.linuxliteos.com/manual/software.html#pparem


Added: I believe Audacity is in the repository where you are using the PPA audacity-team..
Looking at the PPA https://launchpad.net/~audacity-team/+ar...untu/daily  doesn't appear to have Bionic (18.04) support as of yet.
The package (repo) does.. https://launchpad.net/ubuntu/+source/audacity
