SOLVED! Failed to fetch... Hash Sum mismatch

by cc » 2011-04-24 20:58

Code: Select all

My /etc/apt/sources.list:
Code: Select all

Yep, perhaps a problem with debian update server.

OK to use Debian User Forums as a suggestion box?

Several experienced users, including Computer Bob, have recently stated that hash mismatches are likely to occur if a user tries to download a package while a repository is being upgraded (e.g. from offering 6.0.1a packages to 6.0.2 packages).

I hope it will not be too controversial to assume that in a hostile networld, it is important for the future of the Debian project that
  • users be educated to be alarmed by hash mismatches when installing packages
  • users not be unduly alarmed by innocuous temporary problems

Would it be feasible to change the way
  • repositories are updated
  • apt and frontends (aptitude, kpackage, synaptic..) behave when user tries to install a package while repo is being updated?

This is an old thread but I thought I would butt in and offer another reason as to why you MIGHT be getting this error.

This HAD happened to me a while back and it turned out to be my proxy server was serving up an previously cached version of the packages, hence the sum mismatch error.

Well, Today I was trying mirrors left, right and bloody center having the same problem NOT running through the aformentioned proxy. So it turns out that my ISP here in Thailand wasn't too proficient at updating their proxy either. I rang them up, found a lovely English speaking lass who understood my concern and managed to take off their transparent proxy and all was well.

They (the ISP) also mentioned that they don't cache FTP, so if you have no love using HTTP, try FTP. This is of course if none of the above applies (ie: Updating in the middle of an rsync merge or something)
