Thanks, that's good to know. I did disable a repo I'd used for
backports, but replaced with another (I was not being able to connect
reliably to the first one).
After I hacked away at the mountain of non-stable packages,
downgrading them one by one (and probably uninstalling stuff I
shouldn't have), I found this recipe online
http://ispire.me/downgrade-from-debian-sid-to-stable-from-jessie-to-wheezy
...and it did the trick.
I can't say that I'm back to where I was yesterday (I think my frantic
manual downgrading spree may have messed some things up), but at least
the set of non-stable packages in the system is what it was yesterday.
The whole experience has made me *very suspicious* of aptitude.
First of all, this whole disaster happened while I've been using
aptitude to manage my installations.
But there's also this: After setting the sources.list and preferences
file as described in the recipe above, but before running the apt-get
commands at the end, I attempted to run the equivalent aptitude
commands, starting with `aptitude upgrade`. Here's the thing: none of
the `aptitude *upgrade` commands did anything. They all gave the same
output:
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 59 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.
In contrast, `apt-get update` followed by `apt-get upgrade` worked
like a charm.
I'm considering going back to apt, even though most of the advice I've
read on apt vs aptitude leans in favor of the latter. After this
experience, I've lost trust in aptitude.
