According to the PPA it is only covered up to Vivid 15.04. You can still download it, but you need to make a change to the PPA file on your system.
The reason for changing it, when you add a repository with the add-apt-repository
, it creates a PPA based on your distro of Ubuntu that you have. The distro you have is code named Wily
for Ubuntu 15.10. So, the file created for the PPA which should be, /etc/apt/sources.list.d/strukturag-libde265-wily.list
, contains the following line:
deb http://ppa.launchpad.net/strukturag/libde265/ubuntu wily main
so during a sudo apt-get update
you should have seen something like this:
W: Failed to fetch http://ppa.launchpad.net/strukturag/libde265/ubuntu/dists/wily/main/binary-amd64/Packages 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/strukturag/libde265/ubuntu/dists/wily/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
The way to fix it for now would be to change the line in the file for one step back for the PPA so you can install the desired H264 files.
To modify the PPA file for now, press Alt+F2 to bring up a run window. Then type in the following to edit:
gksu gedit /etc/apt/sources.list.d/strukturag-libde265-wily.list
It will ask for your password as this needed elevated level to modify this file. Then make the following change:
deb http://ppa.launchpad.net/strukturag/libde265/ubuntu wily main
to
deb http://ppa.launchpad.net/strukturag/libde265/ubuntu vivid main
Then you can just close the file as it will prompt you to save it. Save the changes, then rerun
sudo apt-get update
sudo apt-get install gstreamer1.0-libde265
It is not recommended to keep a PPA that does not belong to the version of Ubuntu you are running as it can update applications to the wrong versions made for your distro. You should be OK for installing the gstreamer1.0-libde265
. After installing, I recommend to go back and modify the PPA file one more time and comment out that line so that it is not part of sudo apt-get update
until they put out a Wily
version of the PPA.
To comment out, change
deb http://ppa.launchpad.net/strukturag/libde265/ubuntu vivid main
to
#deb http://ppa.launchpad.net/strukturag/libde265/ubuntu vivid main
Hope this helps!
