Problems after Clean Install

I have done a clean install of Ubuntu 18.04, 20.04, Debian 9 and Debian 10
All seems to go great, then when I try to uplod tracks, I get an error saying…
“An error occurred while processing your upload. Please try again in a few minutes.”

No matter what I read, where I look, cant get it to work.
Can somepne help ?

Did you select the option to include the “restricted extras” when installing Ubuntu and if not, are your uploads MP3?. Ubuntu’s MP3 libraries are in the restricted repo due to patent issues.

Also there is a note about increasing the php upload limit in /etc/apache2/sites-enabled/airtime* but I found mine was already 500M.

Take these suggestions with a boulder of salt - I also don’t have a working LibreTime instance.
