No support for versioned package entries

[alexmyczko]

Sometimes when others create Debian packages like listed at:
http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/

where you'd like an entry like this:

+ libcudnn8=8.4.1.50-1+cuda-11.6
+ libcudnn8-dev=8.4.1.50-1+cuda-11.6

Unable to find a version "8.4.1.50-1+cuda-11.6" for the package "libcudnn8-dev"
Unable to apply some actions, aborting

aptitude-robot fails with aptitude exited with value 255

however the following is no problem:

apt install libcudnn8=8.4.1.50-1+cuda-11.6
# or
aptitude install libcudnn8=8.4.1.50-1+cuda-11.6

Is there a chance aptitude-robot could be fixed in this regard?

EDIT: added exact wording of error message above exit status

Hmmm, interesting, thanks. Wonder if it's the two pluses or (more probably) the equal sign in the line. Need to experiment.

[alexmyczko]

my test says it's not the equal sign, tried with a version without + sign.

--show-cmdline creates 'libcudnn8=8.4.1.50-1+cuda-11.6+'

I think there is a "not" too many. Or the "equal" should have been a "plus". Doesn't seem to make sense to me else.

basically said: i tried with a package that is available in multiple versions, and the version string doesn't containt "+", and that gets processed right
