after the next run the command `apt-get update & & apt-get upgrade` I have no problems.
therefore, we can say that this is a temporary problem and it is solved.

the fix is very simple, just replace all
x.has_key('key')
with
'key' in x

probably fallout from the py3 transition

This bug was fixed in the package update-notifier - 0.121ubuntu1

  * replace dict.has_key with key in dict (LP: #1040380)

The update wouldn't apply for me, either with apt-get upgrade or apt-get --reinstall, because it tries to configure update-notifier-common (and fails) before updating it.

But manually editing /usr/lib/update-notifier/package-data-downloader to replace lines like "if para.has_key('should-download'):" with "if 'should-download' in para:", as Julian said above, allowed the update to apply. (I didn't want to try removing it because apt-get was going to remove other packages.)

you should also be able to download the fixed deb from launchpad and install it manually with:
dpkg -i file.deb
apt-get install -f

all work! thanks!
easier to do so:

#under root user
apt-get update
apt-get upgrade

#you see this error, "AttributeError: 'Deb822' object has no attribute 'has_key'" etc...

dpkg --remove update-notifier-common
apt-get install -f

#update-notifier installed, all works!

Thanks for fixing it. I'll rinstall 12.10 but keep 12.04 going as well.

This bug happened again with Beta 1.

I don't see how, there is no has_key in the source anymore
are you sure it was the up to date update-notifier?

And it has happened again with beta 2 during upgrade
