Hi, My Update Manager reports:
62 updates have been selected. 27.8MB will be downloaded
Failed to download package files
Check your Internet connection.
Under details I find:
Failed to fetch http://th.archive.ubuntu.com/ubuntu/...u1.3_amd64.deb 404 Not Found
Failed to fetch http://th.archive.ubuntu.com/ubuntu/....79.12_all.deb 404 Not Found
I checked with a ping to th.archive.ubuntu.com and got a 3 out of 3 success score, so I don't think there's anything wrong with my internet connection.
There are some CUPS updates and some new kernel headers in my update list, but I can't be sure whether these are new updates or hangovers from a previously failed update attempt. I don't want to skip any updates, especially not CUPS updates because I do have some printer issues pending.
I am currently in Thailand, so Update Manager is correct in directing these updates to th,archive.ubuntu.com.
