some months ago I've installed Pure Data on my lubuntu 64 bit, now I'm trying to update my Pd 0.50.2 to a newer version.
When I try to update the software list with "sudo apt-get upgrade", in the result I've got this message: <<The repository "http://apt.puredata.info/releases focal Release" does not have a release file>>.
Therefore, if I write
sudo apt-get upgrade puredata I receive this message: "puredata is already the newest version (0.50.2-3)."
Now, what's the best way for updating Pure Data and do not lose my preferences?
I see that in the download page, there are many packages:
I haven't found on the web many information, so here I am.
I'm not a linux and pure Data expert at all and I don't want to do random things.
