In /var/backups I find
alternatives.tar.0
apt.extended_states.0
dpkg.arch.0
dpkg.diversions.0
dpkg.statoverride.0
dpkg.status.0
and older versions (upto .6.gz) of same files.
I understand it is backup of different dpkg/apt states. But what I do
not find is how to use those files ?
I backup them on other disks, but if my PC crashed, how an I use this
to install a new PC, with same packages ?
I do following commands before my backups, to be able to reinstall,
but maybe they are not necessayer (except that I know how to use the
files)
- dpkg-query -f '${binary:Package}\n' -W >
/var/backups/installed_pkgs.txt
- apt-mark showmanual > /var/backups/manualpkgs.txt
- debconf-get-selections > /var/backups/debconf.txt
