Well, BOINC is up to v7.0.28 and I'm still getting the Computation Errors, and now for some reason it won't connect to the Internet anymore. I've tried closing BOINC and relaunching to no avail. I've even rebooted the computer. On top of the issues I'm having with Ubuntu 12.04 and other applications that were working before I updated, now BOINC isn't working properly either. This is not boding well for Linux and open source applications in my books.

..still getting the Computation Errors..

Which project is this on, please?
CPU or GPU?
Got a link to one of the computation errors?

You make it sound like there's only one sort of computation errors, by stating them as "the". This is wrong, there's plenty of other cases that give errors. So while BOINC 7.0.25 had exit code -1, exit code 1 and exit code 193 errors, that doesn't say that 7.0.28 has them as well.

I'm running SETI@HOME. Every file it downloads goes to Computation Error as soon as the download is complete. I did the standard install of BOINC 7.0.28, so I assume it is GPU as that was what I was running before. However, I have to say that the new version of UBUNTU will not identify my grahics card, in fact it thinks my PC is a Laptop, a common problem that lots of people seem to be having with Ubuntu, so that may be contributing to the problem. Sorry, don't know what the error code is as there is nothing in the log either. Since I just wasted two day trouble shooting this, I'll just wait for both BOINC and Ubuntu to come out with new releases. Hopefully that will solve my problems.

If your GPU isn't detected, it isn't being used.
I asked for a link to one of your errors, at the project web site. All tasks/results have their own link, you can get at them from your account at Seti->Tasks. Right click any of the ResultIDs on the left, copy their web address and post as a link here.

Else post the first 20 to 30 lines of your BOINC start-up messages. That way we can see (enough) info as well.

I'm having the same problem...

Ubuntu 12.04 LTS with BOINC installed from Ubuntu Software Centre.

Here's a link to my tasks.

Doesn't even run for a second, it just immediately fails...

Ubuntu 12.04 LTS with BOINC installed from Ubuntu Software Centre.

Yeah, but that's 7.0.24, not 7.0.28

See the whole of this thread at Seti (wait patiently, the forums are slow today). And also check this thread at Seti. Both will explain your problem (which is 7.0.24 to be honest).

mine is saying that
app_info.xml does not have a usable version of SETI@Home enhanced

??? Bob

Either post about it on the Seti@Home forums, or give more information. Such as your system, your OS, what you (want to) use the app_info.xml file for, etc.

If you don't want the message, fully exit BOINC first, then navigate to your BOINC Data\projects\setiathome.berkeley.edu\ directory, remove the app_info.xml file. Next restart BOINC and reset the Seti project. At the next scheduler contact BOINC will download the default applications and starts using those.

By the way, your question has, as far as I can see, nothing to do with the thread you posted in. Next time, please just post your question on its own in its own thread and while you're at it, don't be as secretive about everything. It's very difficult to help you when the first thing we have to do is pull all kinds of information out of you, info that you yourself could've easily given at the get-go.

ok it was an addendum to the first complaint.
I've upgraded to 7.0.28 and am getting Computation errors. the advanced event log is giving the app_info.xml does not have a usable version.

am running Kubuntu 12.4 and have downloaded the debian Apt-get version of BOINC
the file in question is not in the directory so cannot remove, tried that.
and I'm trying to run SETI@home which I have been running successfully for many years. I upgraded from Kubuntu 11.10 to 12.4 and the problems started. have installed all the upgrades.

I have totally removed BOINC 7.0.28 and reloaded a fresh copy with the same result.

when trying to run the task bar gives the "Computation error" code.

Bob

the file in question is not in the directory so cannot remove, tried that.

You were in the active BOINC\projects\setiathome.berkeley.edu\ directory? I ask as with Linux versions it differs where the data directory is when you go from e.g. a Berkeley installer to a repository installer. It's very well possible you have two data directories and are checking the wrong one. Or that your BOINC is using 'the wrong one'.

I have totally removed BOINC 7.0.28 and reloaded a fresh copy with the same result.

The thing is, as far as I know even in Linux, the data directory is separate from the BOINC programs. So you can remove BOINC all you want, but as long as the data directory with the science applications, with the tasks, with the anonymous platform file etc. is kept in place, it won't fix the message about the old version.

when trying to run the task bar gives the "Computation error" code.

In your Seti account on the web site->View tasks->Errors->when you click on the details of any such task showing computation error, it shows in more detail in the stderr.txt what the exact problem is. There's not just one computation error code, there's several tens of them.

Ok, so I realize this is a seriously old thread, but I just googled computation errors on BOINC, and this is where I ended up.

I recently installed 7.0.28 on Ubuntu 12.04, and I'm getting lots and lots of computation errors.
I suspect the error is on the BOINC software because I get errors on multiple projects such as QMC, Edges, Eon, Primaboinca, and WEP M2.
I don't think there's an issue with my computer, because it's working flawlessly with an old version of the BOINC manager and I'm not experiencing any problems when running other programs.
Also, I'm getting errors on non-CPU projects like FreeHAL and WUProp which hopefully should not be affected by CPU overheating problems or such.
I am also running a few GPU projects such as Primegrid, Moo wrapper and Collatz, and these seems to be unaffected and does not get computation errors.

This is not a huge issue, I just backed down to 6.10.58 that I was running before, and everything is working OK again. Just to let you know there might be something to look into.

I'm getting lots and lots of computation errors.

What kind of errors? Mind linking to any of your computers on the projects, or to any of the erroneous tasks? As without, it can be anything.
