I had some problems installing v7.5.1 on my Ubuntu 18.04.4 LTS, so I thought I could tell you what worked for me:

0. Install GPU related drivers and OpenCL libraries, if you want to use your GPU (essential for Covid-19).

I had my Nvidia drivers already installed, so I only had to do:

Code: Select all

sudo apt install ocl-icd-* opencl-headers

1. Download all packages from the website: fahclient_7.5.1_amd64.deb, fahviewer_7.5.1_amd64.deb, fahcontrol_7.5.1-1_all.deb

2. Try installing fahclient_7.5.1_amd64.deb first:

Code: Select all

sudo dpkg -i fahclient_7.5.1_amd64.deb

This is will fail with the following error:

Code: Select all

(Reading database ... 374643 files and directories currently installed.)

3. Run the following command to fix the above error:

Code: Select all

sudo update-rc.d FAHClient defaults

4. Try installing fahclient_7.5.1_amd64.deb again:

Code: Select all

sudo dpkg -i fahclient_7.5.1_amd64.deb

5. Try installing fahcontrol_7.5.1-1_all.deb:

Code: Select all

sudo dpkg -i fahcontrol_7.5.1-1_all.deb

This will fail because python-gnome2 is missing.

Code: Select all

Selecting previously unselected package fahcontrol.

6. Install python-gnome2 dependency

Code: Select all

sudo apt-get install python-gnome2

7. Install fahviewer_7.5.1_amd64.deb

Code: Select all

sudo dpkg -i fahviewer_7.5.1_amd64.deb

8. And you should be ready to go.

The executable is in:

Code: Select all

/usr/bin/FAHClient

To start the application, issue the following command:

Code: Select all

systemctl start FAHClient

The web control is at:

Code: Select all

https://client.foldingathome.org/

Choose 'Any disease' at the drop down menu in particular if you want to contribute to Covid-19.

Apparently there are no WUs currently. My GTX970 is idle for some time now due to:

Code: Select all

10:48:37:WARNING:WU01:FS01:Failed to get assignment from '65.254.110.245:8080': No WUs available for this configuration
10:48:37:WU01:FS01:Connecting to 18.218.241.186:80

10:48:38:ERROR:WU01:FS01:Exception: Could not get an assignment

EDIT: Now, I'm picking jobs for my GPU without any delays.

I hope somebody finds this information useful.

Go science!!

Same here - please fix this

Hello, I think I have been able to install everything successfully. But when I run /usr/bin/FAHClient, I encounter the following error: 13:36:16:ERROR:Exception: Failed to open 'log.txt': Failed to open 'log.txt': Permission denied: iostream error: Permission denied

Could you please help?

Don't try to run from /usr/bin/FAHClient executable, use the service command that has been set up by installer : "systemctl start FAHClient".

excellent quick guide for setting up on ubuntu are its variants.

Teh servers are struggling to keep up with demand for work units, please be patient as the science team are working hard to spin up additional servers and work, neither of which are trivial exercises.
