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.

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

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.

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:

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 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!

Could this be a python problem that myself and others observed with new installs of linux mint 18.3?

This solved the QC error problem for us:

wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb

sudo dpkg -i python-support_1.0.15_all.deb

It looks very promising, but I have reached my daily limit due to the errors. Maybe someone else can try it?

There is a similar python version issue with the FAHControl app over at Folding@home. Apparently Ubuntu 18.04 has python 3 installed so you may have to install python 2. Here is the link over at the folding forum

https://foldingforum.org/viewtopic.php?f=96&t=30778


For the QC app I've found:

linux mint 17.3, the python version is 2.7.6 and it works fine.

Linux mint 18.3, the python version is 2.7.12 and the QC app errors out.

As posted above installing the python-support_1.0.15_all.deb package solves the problem

wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb

sudo dpkg -i python-support_1.0.15_all.deb

You can check the python version with:

python --version
or
python -V

On my SuSE Leap 42.3 Linux python is 2.7.13. Is this the problem? By the way, I have followed an online course on python via edx/Berkeley and I don't like it. They made use of Jupyter Notebooks which is an Interactive python developed at UC Berkeley campus, whose authors received a prize by the Association for Computing Machinery,as reported in the Berkeley Online Newsletter which I receive. But why use an interpreter? CERN uses Scientific Linux which is RedHat plus some CERN libraries, and VirtualBox in its LHC@home projects, which I run on Windows 10 and SuSE Linux. I would gladly help GPUGRID CPU tasks but they all fail.
Tullio

@Tullio, Is there a way on openSuse to "force" the QC app to use python 2.6?

At the folding forum, there are instructions for openSuse users to set up fahcontrol to use python 2.6 vs 2.7.

See step 2 at this link.

https://foldingforum.org/viewtopic.php?f=89&t=30335

@Tullio, It looks like the QC app looks for python 3.6.3. I'm not sure what you need to get it working on openSuse. Sorry.

Perhaps the developers could release a version of the QC app for python 2.7?

This solved the QC error problem for us:
wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb
sudo dpkg -i python-support_1.0.15_all.deb

I guess you already tried the reset, right?

I think on some projects (maybe Rosetta or Folding, I don't recall) they are talking about recent changes concerning static versus dynamic linking of Linux/Ubuntu libraries that are causing problems, but I know nothing about that. Good luck.

When I update the kernel modules of VirtualBox after a kernel upgrade on my SuSE Learn 42.3, the installer says it found Python and proceeds.I must confess I don't know much about Python despite taking a course and I would not like to download a version that the VirtualBox installer cannot use.Since VirtualBox is vital for me to run the CERN projects of LHC@home, I am not fiddling with it. Sorry.
Tullio

There has been a recent discussion of the differences and incompatibilities between Python 2 and Python 3 on BOINC's GitHub page - primarily directed at Python as used on the server, but it may be helpful here.

Port to Python3 #2475

Keep reading through (it's a long thread): there are some pointers to useful tools like 2to3 and python-future towards the end.

The only time when GpuGrid scientists will condescend to involve themselves in dialogue with you is when they have something they want so enjoy the experience.

I installed build-essential which includes gcc on my mint 18.3 clean install.

sudo apt install build-essential

I installed build-essential which includes gcc on my mint 18.3 clean install.

It's like a little nightmare.

- VirtualBox VM with Mint 17.3
- sudo apt-get update/upgrade
- sudo apt-get install gcc ("gcc is already the newest version")
- sudo apt-get install buid essential
- wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb
- sudo dpkg -i python-support_1.0.15_all.deb
- sudo apt-get install boinc-client boinc-manager (7.2.42)
- gcc -v = 4.8.4
- python --version: 2.7.6

Give it a try, although I doubt it will solve the gcc problem you have (but one can always hope)
