Perhaps I can clarify. Just as an experiment, I took a buster system that had a minimal installation of tasks "ssh server" and "standard utilities", plus: etckeeper git git-man patch rsync sudo apt-show-versions aptitude. I ran the attached file simultaneously requesting 271 packages, and thereby installing 1558. Everything was installed and configured correctly. I then reran the attached file but edited: install → purge, followed by apt-get --purge autoremove a couple of times. After all this, I was back at the original 350 packages that were present before I ran the attachment. Again, no problem. > Unless you use one of the --force options (at your own risk, of course) > dpkg will refuse actions that go against (Pre-)Depends, Conflicts and > Breaks. > > The difference between dpkg and apt in this regard is that dpkg acts > only on the set of packages it was provided. Having cleared the cache before I started the above, I now had the 1558 .deb files sitting in the cache, so to reinstall them I ran # dpkg -i -R -E /var/cache/apt/archives/. At the end of that process, the final messages from dpkg were: Errors were encountered while processing: /var/cache/apt/archives//fvwm-icons_20070101-4_all.deb /var/cache/apt/archives//gawk_1%3a4.2.1+dfsg-1_i386.deb /var/cache/apt/archives//libmotif-common_2.3.8-2_all.deb /var/cache/apt/archives//libxm4_2.3.8-2_i386.deb /var/cache/apt/archives//lilypond_2.19.81+really-2.18.2-13_i386.deb /var/cache/apt/archives//ntfs-3g_1%3a2017.3.23AR.3-3_i386.deb boot-info-script fig2dev testdisk xpdf Respectively, the 10 errors were: pre-dependency (4 off), file missing during pre-install, pre-dependency, gawk missing (2 off), ntfs-3g missing, libxm4 missing. In addition, this error message occurred during the run: systemctl preset failed on ModemManager.service: No such file or directory There was no problem setting up modemmanager when I was using apt-get. > User: dpkg, remove this package > dpkg: nope, this will break these other packages > User: apt, remove this package > apt: sure, in addition these other packages must be removed because > they depend on it > User: ok, go ahead > apt: dpkg, remove this set of packages > dpkg: sure, done > > User: dpkg, install this package > dpkg: nope, it depends on these other packages that are neither > installed nor were provided at the same time > User: apt, install this package > apt: sure, in addition these other packages must be downloaded and > installed to fulfill dependencies (and recommendations) > User: whatever, do it already > apt: ok, downloading... done > apt: dpkg, install this set of packages > dpkg: sure, done So—the "dim memories": Years ago, when I had to install duplicate systems on several machines, I would capture the cache from the first installation on a 1GB Jaz drive, and use it to install the others. (My systems were considerably smaller then.) One useful command when doing this was dpkg --configure -a whenever dpkg got jammed up, followed by repeating the dpkg -i command (which explains using -E above). Cheers, David.
