I recently had to opt for cleaning my cache through
apt-get clean after getting lots of GPG errors during update. But it's created another problem for me since I want to create an "APTonCD" for backup.
I want to know how I could just get all the packages I've installed on my computer so that I could include them in my APTonCD. Is it possible to achieve that by selecting all installed packages in Synaptic for reinstallation but choosing to download those files only. I hope that option will leave my installed packages intact.
