Package: debtree
Version: 1.0.10
On debian jessie, I execute:
$ debtree python-gtk2 --arch=armel --no-recommends --no-alternatives
--no-provides
which yields:
....
"python-numpy" -> "libblas3" [color=blue];
"libblas3" -> "libquadmath0" [color=blue,label="(>= 4.6)"];
But from the following link you can see there is no armel arch available
for libquadmath0: https://packages.debian.org/jessie/libquadmath0
Thus, I conclude that debtree is incorrectly reporting. Additionally, I'm
not certain where feature requests go, but support for JSON output would
certainly be helpful/preferable versus going straight to graphwiz,
particularly considering that there is not otherwise a clear recipe for
dependency traversal via traditional APIs.
