This is a new install of Ubuntu 18.04 on new hardware. If you upgraded, may a clean install would work?

I'll retry with a fresh installation...

I just got one myself on Ubuntu 16.04. Maybe it was a recent update that did it? It will take someone with Linux expertise to figure it out.

But all the others are erroring after 35 seconds too.

Maybe something in the work unit changed. I have been off of QC for a few days, and it was working before.

I try to use Ubuntu 18.04, but i have all errors:

I am running 17.10 and am getting upgrade requests for 18 but have not jumped to it.

I have an RX570 using AMD PRO-17.50-511655 and I cannot use a "blank" screen saver or turn off the monitor as the gnome desktop locks up after a while. This seems to be a known Bug #1729028 but that bug was closed as no one has been complaining about it recently.

If 18.04 fixes this problem I may upgrade but I hate to mess with a working Linux box.

Are you using gnome desktop? If so, can you laave the system running overnight with the monitor turned off?

They are still failing for me. Is anyone looking into this?

NOTE: I use an app_config to allow only one work unit to run at a time (on 4 cores), so it is not the "startup problem".

I tried a fresh installation of Ubuntu 17.10 and ALL my wu crashed after 5/10 minutes with the same error:

I use Lubuntu

I tried a fresh installation of Ubuntu 17.10 and ALL my wu crashed after 5/10 minutes with the same error

Today, with fresh installation of Lubuntu 14.04 with no updates (and an older version of Boinc). Same errors.

Today, with fresh installation of Lubuntu 14.04 with no updates (and an older version of Boinc). Same errors.

I think that proves it is a problem with the application (or data). I had thought it might be due to a recent security update for Ubuntu 16.04, which would place it on the same level as Ubuntu 18.04. But that is not the case. Thanks for checking.

Here are some more clues. I have an install from on or about April 28, 2018 that works fine. Starting on or about April 30, many new installs seem to fail. I tried a new install on May 5 that failed.

In looking at run logs, a successful task runs for about 30 seconds, downloads a small amount of data, gives this message:

CondaValueError: prefix already exists: /var/lib/boinc-client/projects/www.gpugrid.net/miniconda/envs/qmml

then starts running on all 4 "CPU's" to a normal completion.

An unsuccessful task starts up, downloads data for about 5 minutes, then gives the following error messages and aborts.

It appears that something happened to the job setup between April 28 and April 30 that causes a new install to have problems.

As a test, I copied the entire /var/lib/boinc-client/projects/www.gpugrid.net/miniconda/ folder from the known good setup from April 28 to the new setup that I was working on today. With that in place, the new install completed a QC tasks normally and has started another one.

Computer ID for the new setup is 476647 if you want to take a look. My Linux skills are limited so it took me a while to get the right combination of copy, paste, folder location and security permissions. If you look at tasks processed, you will see several errors until I stumbled onto the magic solution.

Please let me know if you have questions or need more information.

Can you check if you have the gcc package installed? AFAIK it is not by default.

Thanks

Toni,

gcc was not installed when I ran the first test. I installed it then started getting different error messages until I copied the miniconda folder.

Hope that helps.

Can you check if you have the gcc package installed?

I update the gcc on old lubuntu to 4.8.4 version.

I tried it on a different machine, a Ryzen 1700 with Lubuntu 17.10.1.

First I checked the gcc: "gcc is already the newest version (4:7.2.0-1ubuntu1)"
Then I updated everything, and am now running Linux 4.13.0-41
Finally, I downloaded a single QC work unit (4 cores). It ran for three minutes.

Problems with all -buntu distro. I'll try a Fedora...

As I wrote in News all CPU tasks on my SuSE Leap 42.3 Linux fail miserably. GPU tasks on the same computer, a SUN Workstation with Opteron 1210 and a GTX 750 Ti board complete and validate.
Tullio

I'm getting the same error on Arch Linux.

I should need an explanation. When I have a Linux task waiting to start and I click on its Properties I see an executable called wrapper that is very similar to the vboxwrapper of LHC@home tasks. But when it starts and goes on for about 5 minutes the Linux (and UNIX) "top" command show a "python" running. Which is the relationship between the two executables?
Tullio

Surely the major distributions should work as long as you have gcc installed.

Something to try is to reset the project. This should delete the (large-ish) miniconda executable and download it again at the next start (which takes a couple of minutes). Beware, reset stop GPU WUs too!

Reset is likely necessary if you upgrade the OS.
