Comment 6 for bug 312491

A comment that I received via eMail:
synaptic should not even start the installation/update if not enough space is available. It normally says how much more space will be needed, and I had a little more free space than needed, but it was not enough, as the update itself required more space then it would occupy after completed update, I suppose.
two: old states of packages should always be kept as a fall-back in case update fails. Only if update completed successfully the old packages should be deleted, for only freeing space did not solve the problem for me. After I had run into too little free space, I was left with some broken packages I could not reinstall or uninstall.
