is this install method not working and PD needs to be compile from source? https://puredata.info/docs/faq/debian <https://puredata.info/docs/faq/debian>
Are you trying to install pd vanilla or extended? As stated on that page, the repos were for pd-extended. Vanilla should be in standard Ubuntu repos already, though I believe 0.46.7 may be the most current release available there. Since pd-extended is somewhat deprecated now it is stuck somewhere around 0.43, so you will definitely not get updates searching for that.
OMG! sorry, I made a mess... I had forgotten about the fact that before summer I did try to install extended but then I finally installed vanilla. I never removed the repos from the apt system. Now in my messy head both got mixed. thanks!
