I discovered the final source of my reported problem. While I had the same symptoms at both my office Linux (U9.10) and 3 home Linux desktops (U9.10) I assumed the common thread was the repositories. The error with my office machine cleared for some unknown reason and I discovered I had a similar issue with a home Windows machine updating iTunes. In a bug against the iTunes "invalid signature" keyword a suggestion was made that using a different router cleared the problem in a number of cases.
I reset my router to no avail. I next reset my cable modem and, low and behold, the problem not only cleared (hash sum mismatches) but the network speed increased as well. It is unclear to me why, assuming apt-get and aptitude use tcp as a protocol, that if there were a problem with a router or other network error, the tcp packet would fail the packet and the underlying application would fail on network IO. Browser pages worked fine, ssh, scp, vnc, etc, worked fine. My question now becomes why does apt-get and aptitude fail? If a comment could be added to shed some light on this all would appreciate it. Thanks.
