Fedora 31 problems

[Neill]

Upgraded from fedora 30 to fedora 31 with the following problems:

1. FAHClient failed to start
2. FAHControl failed with

File "/usr/bin/FAHControl", line 58
if sock.recv(1024).strip() == 'OK': print 'Ok'
^
SyntaxError: invalid syntax

I was running version fah 7.4.4.1
Thanks - any help is appreciated.

[MeeLee]

Current versions is 7.5.1
Install that one and report back.

[Neill]

Thanks, I installed 7.5.1 and got the same problem. Then I found out that Fedora 31 had switched to python 3 as the default. To fix the problem change the 1st line of /usr/lib/FAHControl from
#!/usr/bin/env python to #!/usr/bin/env python2
Thanks for your help, Neill.

[JimboPalmer]

I thank you for reporting back what worked, our help improves if we know what works to fix issues!

[MeeLee]

Please elaborate on what file you've changed?
FahControl does need Python 2 dependencies, which also are installed, but somehow not called upon in Ubuntu.
However, Python 3 has some different syntaxis, so there might be some issues with bugs.
If your solution works, let us know which files you've changed, and I'll see if the same is true for Ubuntu and it's variants.
PS, if it's true for Ubuntu, the same will be true for Debian.
Then those users who're still running Debian 8 (Jessie) or Stretch (9), can update to Buster (10) ; or those running Ubuntu variants based on Bionic Beaver (18.04), could update to Disco Dingo (19.04) or Eoan Ermine (19.10).

[MeeLee]

I have been playing around with Ubuntu 19, and the solution offered doesn't work.
The location of FAHControl here, is in /usr/bin instead of /usr/lib.

What I think is happening, is what happened to me, when I updated Lubunu 18.04 (or 18.10) to 19.04.
right after the update procedure, it was possible to run FahControl.
However, as soon as more system updates were done (I presume dpkg decided that a python package was no longer needed) it broke compatibility, and FAHControl no loner worked.

That being said, I can run FAHClient (CPU) very nicely on Ubuntu, so I would presume it would work the same for Fedora/Redhat/CentOs/Debian/Mint.
I haven't tried GPU, since I have no access to that yet.
I presume as soon as you do a full upgrade, your system will do the same as mine, and break compatibility.

[wdanwatts]

On my Fedora system, after upgrading to 31 from 30 the FAHControl icon wouldn't bring up the GUI.

I changed the first line of /usr/bin/FAHControl from:
#!/usr/bin/python

to

#!/usr/bin/python2

and then the icon worked again.

[giuliohome]

Thank you! That worked for me, I had the exact same problem.
Now please, help me for my next issue please

Code: Select all

Connection Error: 111: Connection refused
ERROR on connection to 127.0.0.1:36330: [Errno 111] Connection refused

I think I added the port to the firewall (not 100% sure I did it well): which are the correct instructions? (for Fedora 31)
Notice that I also stopped the firewall momentarily just to check: so I'm pretty sure it isn't the cause.
Thank you again!

[giuliohome]

Anyway a positive news is that (except for the error above if I run FAHControl..) I have started the client and the viewer and all the rest seems fine: my cpu is working at 99% for Folding@Home already since some hours ago... (we all hope it might contribute to finding something against covid19 asap)

[giuliohome]

Ok, solved the problem of "connection refused" from FAHControl: somehow I had set the wrong number, now it runs and looks much better.
FYI I still see an error in the console, don't know if it is important

Code: Select all

[giuliohome@localhost ~]$ FAHControl

[wdanwatts]

After my last update in Fedora 32, I again had to change the first line in /usr/bin/FAHControl from:
#!/usr/bin/python

to

#!/usr/bin/python2

and then the icon worked again.
However, my gpu won't run. The log shows:

Help!

[wdanwatts]

I looked at "Nvidia GPU error INTERRUPTED (102 = 0x66)" and tried what was suggested (commenting out the line in /etc/OpenCL/vendors/pocl.icd) and the GPU is now engaged in calculations again. I'll update more when I can compare output rates.
It LOOKS like the computation rate is the same (Yes. It is fully back as before.)
