my update manager fails updating Version 2:188.8.131.52.0. I tried to redo update for a couple of days now, but this particular one fails every time. The error message is:
W: Failed to fetch http://security.ubuntu.com/ubuntu/po...tu8.1_i386.deb
404 Not Found
Aside from the obvious 404 (try the link), any hints on this? Tia.
