Package: apt If one hasn't used one's computer in a while, one will get: Err:5 http://opensource.nchc.org.tw/debian unstable/main amd64 Packages.diff/Index Couldn't find the start of the patch series
Well, how about saying Warning:5 http://opensource.nchc.org.tw/debian unstable/main amd64 Packages.diff/Index Couldn't find the start of the patch series Getting the entire file instead. Else the user thinks they need to rescue the situation.
