Because it's out of date (apparently). How do I safely remove this ppa? By which I mean using ppa-purge as that seems the best tool. (In the context of installing android studio.)

  • Not sure what you mean with "safely", but you can just remove the files that list this ppa, or comment the ppa out in those files and you would have done it. – Ziazis Oct 26 '17 at 13:20
  • @Ziazis yeah, would've preferred to use the purge utility. thanks tho. – Thufir Oct 26 '17 at 13:26
  • So what happens with ppa-purge? Doesn't it work for you? – DK Bose Oct 26 '17 at 13:35
  • I assume you want to use the ppa-purge because you installed something and want it to be removed? Because if nothing was installed it makes no sense to use that. – Ziazis Oct 26 '17 at 13:37
  • @DKBose no, it comes back with: E: The repository 'http://ppa.launchpad.net/paolorotolo/android-studio/ubuntu artful Release' does not have a Release file. and that's it. – Thufir Oct 26 '17 at 13:42
  • @Ziazis ok, thanks, I'll just comment out then :) – Thufir Oct 26 '17 at 13:43

curious as to why ppa-purge wouldn't remove those ppa's, though.
