[Bug 1448527] Re: i dnot know excatly

[Steve Beattie]

Thanks for taking the time to report a bug and help make Ubuntu better.
In this case it looks like you have a probable transient network error,
as the dist-upgrade log is filled with messages like the following:

  'W:Failed to fetch
http://archive.ubuntu.com/ubuntu/dists/vivid/universe/source/Sources
Cannot initiate the connection to archive.ubuntu.com:80
(2001:67c:1360:8c01::19). - connect (101: Network is unreachable) [IP:
2001:67c:1360:8c01::19 80]

which indicates that update-manager could not reach
http://archive.ubuntu.com. Should the problem continue to exist, you
would need to contact your Internet Service Provider. Thanks.
