Ubuntu – Can’t re-enable PPAs long after upgrade to 12.10


I upgraded from 12.04 to 12.10 some time ago. I realize now that many of my PPAs were automatically disabled (as it always happens) Now, the issue is that I can't re-enable them, the Software Sources GUI won't let me. I can un-check already checked PPAs but that's it. I can't neither edit nor remove nor re-enable any of the automatically disabled PPAs.

For example, PPAs for Google CHrome, Dropbox, and Wine were disabled upon upgrading. On Google Chrome this reflects in my system still running version 24.0.1312.52 when the current version of this browser is 25.0.1364.172 (since March 12th)

How can I fix this?

By request here's the content of the .list files for Dropbox:

# deb http://linux.dropbox.com/ubuntu quantal main # (desactivado en la actualización a quantal)

and Google Chrome:

# You may comment out this entry, but any other modifications may be lost.
# deb http://dl.google.com/linux/chrome/deb/ stable main # (desactivado en la actualización a quantal)

FYI: "desactivado en la actualización a quantal" means "deactivated during quantal upgrade" in Spanish.

I see the items for DropBox and Google Chrome here, but not Wine. Without the "Wine" entry, I can't help you figure out where you can reenable that.

In the mean time, in the lists for DropBox and Google Chrome, remove the # at the beginning of the line starting with deb, then save. Then, sudo apt-get update; sudo apt-get upgrade. That should upgrade Chrome and DropBox correctly.
