Hello All, Last few days my net connection drops randomly or slows down to a crawl. As a result, there are several timeouts during package downloads. When a download timeout occurs, pacman aborts with "invalid or corrupted package". Is it possible to detect which package is corrupt and invalid, so that it can be downloaded? When it happened with one package, I deleted it manually and next time it worked but when several packages get timeout, its hard to detect the failing one. Does pacman has built-in retry functionality? Here is the complete log. ------------- :: Starting full system upgrade... resolving dependencies... looking for inter-conflicts...
