Hello, Related with my previous problem trying to build a package with a missing dependency in saucy, I wanted to try another approach : - build a custom debian package for that missing dependency (alembic) on saucy - put it on a server/mirror somewhere as custom debs, so the build can find it ( I guess there is a way to do this already ? ) But then I stumbled on another problem : The ubuntu server don't have any saucy packages any longer, which means I cannot test my package dependencies (sqlalchemy for example)... http://archive.ubuntu.com/ubuntu/dists/ so I was wondering, where does the ros build system find the packages for the deprecated ubuntu releases ? Is there a ros ubuntu package mirror somewhere that doesn't delete old releases' packages ? Is it worth it to build a package for a deprecated release, just to make the build work for indigo ? Or should the ros build system instead not force me to support unsupported ubuntu releases, somehow ? Thanks for any input on this. Please let me know the best way for me to release a package using alembic on indigo. -- AlexV
