might problem?

when click on first url, reveals problem:

not found

requested url /ubuntu/dists/jaunty-backports/main/binary-amd64/packages.gz not found on server.

jaunty unsupported , has been 8 months now. when last time tried update?

if running jaunty need upgrade either re-installing supported version or upgrading in situ. latter uncertain because need use old-releases repository , upgrade via karmic unsupported. fresh install preferable, in opinion.

that, of course, if running jaunty. if running lucid or later , somehow there residual jaunty lines in sources.list, needs editing. version of ubuntu running?
