Do you mean creating a local repository for the two debs I need, adding that repository to /etc/apt/sources.list and running apt-get update? The two packages I want to install are already in the squeeze repository. > For safety you should probably also have the debs of packages > currently installed so you can revert if something goes wrong. > > If you didn't clean apt's cache these will be in > /var/cache/apt/archives, That directory contains only 123 deb files; obviously many more than 125 are currently installed.

I looked at the website, it would be quite an effort to find a date which would cover the current state of all packages installed in the box. I would doubtless miss many. > 3a. use dpkg --force-depends to remove python and python-minimal > > dpkg --force-depends --purge python python-minimal If I understand it correctly, --force-depends will warn me of broken dependencies only; it will not remove package chains which will not work when those two packages are removed. > 3b. use dpkg to install the stable versions > > dpkg --install <stable deb files> As the two files I want are already in old stable (squeeze), and that is where /etc/apt/sources.list points to, surely all I would need to do is merely list them. > Alternatively you can also use > > dpkg --force-downgrade --install <stable deb files> > > but my feeling is that purging and installing is safer. Probably, but setting up a reverting backup as you described does not inspire confidence. Perhaps it would be better to do without printing - -- I do not have another printer -- until I can upgrade to Wheezy in a month or two. I could live with that option but with bad grace. > 4.
