Well this should also mention how # aptitude safe-upgrade # aptitude safe-upgrade or # aptitude full-upgrade # aptitude full-upgrade will do more sometimes than just the single versions. Because else the reader must somehow read between the lines to figure it out. It would be nice if all children would know that flushing the toilet twice sometimes helps, but some will just give up after the first failure. Especially upon seeing "E: Unable to correct for unavailable packages" they might abandon hope. So maybe that should also say "E: Unable to correct for unavailable packages. Maybe try running again..."
