apt-get update failing when mirrors are being updated

[antonio]

We have a server that is mirroring every single apt repo our infrastructure depends on. Those mirrors are imported to local repositories, which are then published. There is a cron job running several times a day that updates the mirrors, re-imports the contents to the local repositories and runs aptly publish update.

When another host is running apt-get update and the sync job is being run (which by the way takes around 20 minutes), we are sometimes experiencing the following error in the client:

According to this comment and also this one, this could be an issue in the design of apt, but I'd like to get a second opinion if possible.

Thanks!

PR #354 is first step towards fixing hash sum mismatch problem

I think this has been solved by introducing Acquire-By-Hash support. See #664

Closing this issue. If there is still anything concerning this issue not covered by acquire by hash please comment.
