Hello,
When I used aptitude, I noticed that aptitude does not have an
error handling mechanism. When I `aptitude update`, if the network is broken
(like dns problem, route problem), it can not connect to the server, so it
reports error, and clean up local apt record. If I stupidly `aptitude
autoclean` then, all my debs are gone.
And, during the update, if I find something error, and press C-c,
OK, apt record broken, just leave a little..
Why does aptitude do that?
