After that, running sudo apt-get update- This is what I got:

http://ppa.launchpad.net/alex-wv/pulseaudio-equalizer-ppa/ubuntu xenial Release' does not have a Release file.

manpage for repository creation and user configuration details.

Where are the tweaks located? I tried to open windows manager tweaks in the settings panel, but all it did was make the cursor go into waiting and waiting and finally just went away. Never opened.
