Hi,

I am getting these "checksum or signature errors" while downloading new WU for Rosatte Beta 5.93 on my linux PC.

Here is part of the message :

Anyone got an idea? I had about 5 WU that did not download correctly. But the newest now works.

Keep on crunching!

The transfer of the file to your system was interrupted (incomplete read) before it completed, and therefore the resulting file on your system did not match the required signiture. When several WUs require the same file, BOINC only downloads it once. Since that download failed, all of the WUs that needed the file failed as well.

So, basically, it sounds like your internet connection at the time was interrupted or unreliable. ...or perhaps the project's servers were so busy, they only got a portion of the file sent to you prior to the connection timing out, but that would be very rare.

BOINC will recover itself from such a situation, and request more work and assuming the network is stable later, it will then proceed normally. The project servers basically expect a certain amount of such failures, and so the work will eventually be reassigned to other machines.
