So, the software updater comes up and says that there is a new Ubuntu version, do you want to upgrade it or not. I accidentally press yes. After that I interrupted the upgrade by closing it, and rebooting.

Now I can't download packages, because they're disabled. It says:

Disabled on upgrade to Xenial

How can i stop that upgrade to Xenial?

This is my first question, so I apologize if it's formatted incorrectly. .

  • Which version were you previously on? Trusty? – blade19899 Mar 21 '16 at 11:07
  • I'm currently on Trusty. The problem is Ubuntu Updater thinks that I want to upgrade to Xenial. So it disabled all the trusty repositories in preparation to the upgrade. – Akar Mar 21 '16 at 11:09

I don't know how you managed to get trusty to upgrade to Xenial, which is still not finished. Scheduled to be released on April 21st.

To revert the changes

  • In the Software & Updates go to the tab Other Software
  • enable all the Trusty packages,
    • or rename the xenial part to trusty.

To set it to a default setting do the following:

  • In the dash search for Software & Updates
  • Open Software & Updates
  • select the Updates tab
  • in the Notify me of a new Ubuntu Version, select For long-term support versions

This will only notify you when Xenial, the stable version, is out

Note: None of this is recommended, and might break your system. Use at your own risk.

I'd recommended to do a full backup of everything and just do a clean install.

See the following Q/A for further information on how to rollback to a previous version of Ubuntu:

  • But the repositories is still disabled either way. – Akar Mar 21 '16 at 11:07
  • @Akar This might downgrade your packages, also how did you get it to update to Xenial, its far from finished? – blade19899 Mar 21 '16 at 11:09
  • I have no idea. I just pressed accept or whatever. The repositories are commented out. with another comment that says "Disabled on upgrade to Xenial". – Akar Mar 21 '16 at 11:11
