[Bug 1504252] Re: upgrade from 14.10 to 15.04 fails: x11-utils_7.7+2build1_amd64.deb Hash Sum mismatch

[Brian Murray]

We can see the error in Mainlog.txt:

2015-10-08 19:36:18,405 ERROR IOError in cache.commit(): 'Failed to fetch http://mirror.cov.ukservers.com/ubuntu/pool/main/x/x11-utils/x11-utils_7.7+2build1_amd64.deb Hash Sum mismatch

Dmesg.txt seems to indicate some issues with your network connection:

[38502.972517] vmxnet3 0000:03:00.0 eth0: NIC Link is Down
[38508.154793] vmxnet3 0000:03:00.0 eth0: NIC Link is Up 10000 Mbps

This is something you'll need to investigate manually.

Title:

  Hash Sum mismatch

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I'm attempting to upgrade from 14.10 (with all updates) to 15.04.
  Upgrade seems to progress normally but when what seems to be all
  update packages have been loaded aborts with:

  Failed to fetch
  http://mirror.cov.ukservers.com/ubuntu/pool/main/x/x11-utils/x11-utils_7.7+2build1_amd64.deb
  Hash Sum mismatch

  Same has already been reported as
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1468478 (at least
  as far as I can tell) but for a different mirror, so it doesnt seem to
  be an issue with the specific mirror. As I wasnt sure which logs and
  further evidence would be need I reported this again.

  Best Regards

  Ulf
