undo tracking proposed updates

[65 mustang]

In the "software sources" windows under the "Updates" tab I have checked "Pre-released updates" and installed all the updates. I no longer want to track the proposed updates and have unchecked that item. Now am back to just security and recommended checked. How do i get it to downgrade the packages that it has modified when I had "Pre-released" checked? I want to get back on the stable "Recommended Updates". It seems to have changed what it looks at for updates but did not downgrade the packages. :confused:

Apt never downgrades packages (by itself, you must tell it to do so).

Just wait a while. Or..



pkg2repo () {
[ -z "$1" ] && return
local pkg="$1"
local policy
local cur
local can
local upgrade
for pkg in $@
do
policy=$(apt-cache policy $pkg)
cur=$(echo -e "$policy" | grep Installed | awk '{print $NF}')
can=$(echo -e "$policy" | grep Candidate | awk '{print $NF}')
upgrade="$cur"
[ "$can" == "(none)" ] && can=$cur
[ "$can" != "$cur" ] && upgrade="U: $cur > $can"
repos=$(echo -e "$policy" | grep "$can" -A1 | egrep "(http|ftp|smb|cdrom|nfs|file)://" | tail -1 | awk '{print $2" "$3}')
local msg
msg="%-35s %-45s %s\n"
[ -n "$repos" ] && printf "$msg" "$pkg" "$upgrade" "$repos"
done
}

repo2pkg () {
local frepos=$@
local repos
for pkg in $(dpkg -l | grep '^ii'| awk '{print $2}' )
do
repos=$(pkg2repo $pkg)
if [ -z "$frepos" ]
then
[ -n "$repos" ] && echo -e "$repos"
continue
fi
for i in $frepos
do
echo -e "$repos" | grep -w "$i"
[ $? -eq 0 ] && break
done
done
}




repo2pkg backports
alpine 2.00+dfsg-1~hardy1 http://archive.ubuntu.com hardy-backports/universe
apturl 0.2.6ubuntu1~hardy1 http://archive.ubuntu.com hardy-backports/main
debhelper 7.0.13ubuntu1~hardy1 http://archive.ubuntu.com hardy-backports/main
debian-policy 3.8.0.1~hardy1 http://archive.ubuntu.com hardy-backports/universe
debootstrap 1.0.20~hardy1 http://archive.ubuntu.com hardy-backports/main
devscripts 2.10.39ubuntu2~hardy1 http://archive.ubuntu.com hardy-backports/main


And then you can reinstall those packages:



for i in $(repo2pkg backports | awk '{print $1}') ; do
sudo aptitude install $i/hardy
done


You need -proposed enabled otherwise the functions do not know which repo has them, obviously.

That will then reinstall all the packages to the main hardy repo. Then upgrade and you are good to go.

Or just wait a few days, -proposed ends up in -updates so if you have that repo enabled just wait.
