Greetings;
I have four Debian systems and a couple of them seem to have gotten in
the state that they don't have a full set of packages for some reason.
Is there any way to do a refresh or reinstall of the system to make
sure everything is there? Short of an install from the beginning that
is!! I can figure that one out with no help. ;-)
Many TIA!
Dennis
Dennis,
One way it to get on a "good" system and do: dpkg --get-selections
>complete_good_package_backup.txt
Move that file over to a "bad" system and: dpkg --set-selections
<complete_good_package_backup.txt
followed by apt-get dselect-upgrade
your "bad" system will now install all the packages your "good" system
has listed. This is also a way to "clone" a load out (that and copy
/etc, /var, and any data). I do not think it will remove any pacakges
"bad" has that "good" does not unless it conflicts with the upgrade (but
I have not tried it, so am not sure).
