The following happens every time I want to add a repository - It is not working since I have installed (and then uninstalled) pantheon desktop :(

$ sudo add-apt-repository ppa:appgrid/stable
Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 107, in <module>
    sp = SoftwareProperties(options=options)
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 118, in __init__
    self.reload_sourceslist()
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 613, in reload_sourceslist
    self.distro.get_sources(self.sourceslist)    
  File "/usr/lib/python3/dist-packages/aptsources/distro.py", line 91, in get_sources
    raise NoDistroTemplateException(
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Elementary/next

Uninstalling the pantheon-desktop package is not enough, because it also installs dependencies that will stay. You have to clean up the sytem.

Install ppa-purge:

sudo apt install ppa-purge

Then remove the Elementary PPA with that tool: 

sudo ppa-purge ppa:elementary-os/stable

or whatever ppa you used, e.g. daily --> ppa:elementary-os/daily

  • I have the same problem, and purging didn't help. Ubuntu seems to be back to normal, but os version is Elementary/next – stpoa Dec 01 '20 at 07:02
