Package: apt
Version: 0.9.3
Severity: normal

Hello, I know the --solver option isn't documented yet but I am trying
to test external solvers. When trying to dump the EDSP request I got
the following. A file /tmp/dump.edsp was produced.

debian:/home/treinen# apt-get --solver dump dist-upgrade

So, looks like this was never reproducible until now anymore, so I guess
its kinda unlikely to be reproducible in the future. I am therefore
closing this bugreport, but feel free to reopen if it is by some miracle
still reproducible!


> How does one invoke directly the dump solver?

For the record: /usr/lib/apt/solvers/dump is the solver, just pipe in
whatever you want and it will be written to /tmp/edsp.dump – so, mostly
a lazy way of getting an edsp file out of apt, which is why it makes
this bland dumb-dump joke.
