Hello.

I remember from less than a year ago, you could install pd-extended very easily by just adding a ppa and then "apt-get install pd-extended".

So what has changed? There is no longer package pd-extended.

I ran apt-get update, but looks like ppa is somehow broken:

I'm Lubuntu 15.04

Yes, the ppa hasn't been updated for 15.04. I'm also looking for suggestions on how to install extended here.

Hi PD people, i did install pd-extended in ubuntu 15.04 using the raring repositories. All you need to do is modify your sources.list, run in the terminal "sudo gedit /etc/apt/sources.list", this archive saves the URLs to find the software packages, change the line of the pd repo like that: erase the word "vivid" and change it for "raring". Then you need to run "sudo apt-get update && sudo apt-get install pd-extended -y".

The line must look like this at the end of the editing:

deb http://apt.puredata.info/releases raring main

Fantastic! Can't wait to try this.

Thanks

Switching the repository to look at an older distro worked great! Many thanks! I used Wheezy with no issues so far!

Thanks Juam! works great!
