@whale-av THANKS A LOT I'm back to learning

Thanks a lot for your help! I just install the last version of PD vanilla 0.52 and Gem via terminal like you suggested.
I try to follow this tutorial to create a simple video mixer : https://archive.flossmanuals.net/pure-data/video-gem-tutorials/video-mixer.html
but when I try to create an object "gemhead" or "gemwin" I get : could'nt create.

I went to help section and install Gem package but still can get it working...
What do I do wrong?
Really appreciate any help!

Hello guys, I'm trying to install pd-extended in Ubuntu 20.04 without any success. Actually, I want to create a video mixer with simple effects for live performance and I read I need pd-extended with Gem. Is there another distro I should be using? I tried with the methods described on puredata.info but the PPA doesn't seem to be updatable.
Any suggestions?
Thanks for your time!
