I have installed ubuntu 17.04 on my laptop and everything went well during 5 months but since few days I start encounter this error

When trying to execute the following command:

sudo apt-get install ppa-purge

I get this output:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
ppa-purge is already the newest version (0.2.8+bzr63).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.

  • Could you please update your question with the exact command(s) you run, and their full output ? – Soren A May 17 '18 at 9:20
  • Ubuntu 17.04 reached the end of its support life cycle (and thus became off topic here) in mid January, while Ubuntu 17.10 was released in October. You should upgrade to a supported release or reinstall one from scratch. You’re welcome to open a new question if you have trouble with that. – David Foerster May 17 '18 at 12:16
