DISCLAIMER: I do understand this is about the source packages. I've
never thought about whether or not they ever differentiate from our
debs. Having just run "apt-cache policy", I do see the difference that
can arise.
My search into this went off into a tangent that ended up at..
/usr/share/bash-completion/completions/apt-cache
That has a line that includes:
if [[ ${words[ispecial]} ==
@(add|depends|dotty|madison|policy|rdepends|show?(pkg|src|)) ]]; then
So next I hit up "man apt-cache" to see if man showed how to choose
src over pkg. I didn't get there because "apt-cache showsrc" popped up
first. Ran it to see its output then ended up with...
$ apt-cache showsrc firefox-esr|grep Vers
Version: 91.10.0esr-1
Standards-Version: 3.9.8.0
For the package policy based on last time a system ran "apt-get
update", it could be:
$ apt-cache policy firefox-esr|grep C
Candidate: 91.10.0esr-1
Those just happened to match. My original sample was einstein. Version
and Candidate outputs are different for him. At this second, they are
Version 2.0.dfsg.2-10 versus Candidate 2.0.dfsg.2-10+b1.
That just shows it is capable of plucking out the difference in those.
I usually miss something obvious that negates anything I typed so my
apologies in advance if and when I did here. :)
Hope that helps somehow. Maybe the output from showsrc might be fun to
look at for distraction or something....
