"whatdepends" lists too little. At least, no direct dependencies, which are known to be shown by "showpkg":

Actually, the results of "whatdepends" are quite different in the host system (with the same apt, but p11 as the sources):

# apt-cache whatdepends librpmbuild7
librpmbuild7-4.13.0.1-alt40:p11+348761.100.1.1@1716479364

I'd say they are complete (as expected):

# apt-cache showpkg librpmbuild7

How to reproduce:

apt-0.5.15lorg2-alt100.x86_64
hasher-1.7.4-alt1.noarch


In this case, I rebuilt rpm from sisyphus in hasher first.
Comment 1 Ivan Zakharyaschev 2026-04-22 13:25:25 MSK 
Now I see a part of the reason. The reason is that a specific instance of the named package is selected (in this case, the rebuilt one):

$ ~/hasher/aptbox/apt-cache whatdepends librpmbuild7
librpmbuild7-4.13.0.1-alt44@1776845801

but it's impossible to specify a different one on the command line: 4.13.0.1-alt44:sisyphus+405580.200.3.1@1768927476

[imz@cheval ~]$ ~/hasher/aptbox/apt-cache whatdepends librpmbuild7='4.13.0.1-alt44:sisyphus+405580.200.3.1@1768927476'
W: Unable to locate package librpmbuild7=4.13.0.1-alt44:sisyphus+405580.200.3.1@1768927476
[imz@cheval ~]$ ~/hasher/aptbox/apt-cache whatdepends librpmbuild7-'4.13.0.1-alt44:sisyphus+405580.200.3.1@1768927476'

W: Unable to locate package librpmbuild7=4.13.0.1-alt44:sisyphus+405580.200.3.1
[imz@cheval ~]$ ~/hasher/aptbox/apt-cache whatdepends librpmbuild7='4.13.0.1-alt44'
W: Unable to locate package librpmbuild7=4.13.0.1-alt44

W: Unable to locate package librpmbuild7-4.13.0.1-alt44
[imz@cheval ~]$ 

And this doesn't justify it not showing the direct deps from the newly rebuilt packages, like this one:

$ ~/hasher/aptbox/apt-cache depends rpmspec
rpmspec-4.13.0.1-alt44@1776845801
  Depends: </lib64/ld-linux-x86-64.so.2>
    glibc-core-6:2.40.0.224.573a-alt1:sisyphus+413851.100.2.1@1775135301
  Depends: <libpopt.so.0()(64bit)>
    libpopt-1:1.18-alt1:sisyphus+283609.300.5.1@1630003299
  Depends: librpmbuild7 = 4.13.0.1-alt44
  Conflicts: rpm < 4.13.0-alt6
$

Maybe it doesn't show it because there is an alternative way to satisfy it (not only librpmbuild7-4.13.0.1-alt44@1776845801 , but also librpmbuild7 4.13.0.1-alt44:sisyphus+405580.200.3.1@1768927476)
