Hello,

I've been trying to research if it's possible to install FAH on Raspberry Pi 4 or not. There are some tutorials on Google that claim that it's possible, but when I follow them, I get the error:

I'm running a 64 bit Ubuntu on a Raspberry Pi 4

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal

Is it possible to overcome these errors or am I stuck in a dead-end?

Thanks!
Christoph

I wouldn't pursue this. First of all, ARM CPU WUs are sporadic (I thought in beta?).
Second of all, the Pi4B is not the fastest, not the most efficient.
You'll contribute a lot more running some GPU WUs.

I'm running a 64 bit Ubuntu on a Raspberry Pi 4

Is it possible to overcome these errors or am I stuck in a dead-end?

It's definitely possible to fold on a Pi, because I have 10 Pi's, running 64-bit Raspios lite (Bullseye), which have been folding continuously for more than a year!

And, ignore MeeLee. There are plenty of WU's for ARM processors, and they are doing good work. But, if you have a discrete GPU in another machine, you could consider folding on that for more points, or just to help more.

As per calxalot's reply, you need to use sudo /etc/init.d/FAHClient -v start to run FAHClient. Try that first.

Firstly, set next-unit-percentage to 100(%) in Extra Client options. The default value for next-unit-percentage is 90%. Then get a passkey, otherwise you won't get any bonus points.

Completing 10% of a WU can take more than six and a half hours. You want to return WU's as quickly as possible, to help FAH solve problems as soon as possible. If a WU isn't completed by the Timeout, it will be assigned to another client machine, and you won't get any bonus points (also called quick return bonus). If a WU isn't completed by the Expiration, that WU will be dumped, and you won't get any points (or have helped FAH).

Your System Info is virtually the same as mine.

Regarding your config file options: I've never seen those Process Control options before. You shouldn't have <fold-anon v='true'/>, as it conflicts with <user v='cburgdorfer'/>. Also you don't need <gpu v='false'/>. It's redundant, as there's no GPU to find. The other difference is <power v='light'/>. That needs to be set to 'full' on ARM processors, otherwise you probably won't complete any WU's.

I also have an Extra client option, child, which is set to true, and is the only value missing in Args, listed under FAHClient in your System Info.

Finally, OpenCL returns a different error, but I don't think that matters.

Perhaps, cleaning up your config file will solve your problems.

Using FAH Control. delete <fold-anon v='true'/>, <gpu v='false'/>, <fork v='true'/>, <pid v='true'/>, <respawn v='true'/>, <service v='true'/>, change <power v='light'/> to <power v='full'/>, and add the Extra client option setting child to true, and see if that works. Because it works for me. And, given our System Info is virtually the same, I don't think Ubuntu is the problem.

Refer to Incorrect Slot Options on this page viewtopic.php?p=327416&f=24#p327416 to understand all configure options and their defaults.

Also, I'm wondering why use don't just use Raspios.

Here's my config information (hopefully it's helps you complete your setup, with remote access, for instance, plus it's shows what should happen when it works):

do not try to delete fork, pid, child, respawn, daemon. Those are internal flags that ideally would not be visible in FAHControl. On Linux, with init.d, the client forks and keeps running a child client which does the job.

You may have trouble with init.d, which has been replaced by systemd.

Posted: **Fri Feb 10, 2023 10:14 pm**

You can see some of the extra options in the info section of the log. See “Args:”

Posted: **Fri Feb 10, 2023 10:22 pm**

If you are using the init.d script, use

sudo /etc/init.d/FAHClient -v start

calxalot, it's clear you didn't read my post completely?

Raspios is a version of Linux (Debian). And, Debian and Ubuntu use the same FAH software.
Wouldn't child (which I said to ADD) replace all of fork, pid, respawn, daemon? If not, why do my Pi's work, but the O.P. Pi doesn't work?
Do you know how the internal flags were added? Was it by the O.P. or the software? And, they were in config.xml. Nothing to do with FAH Control!
How about trying to solve the problem, rather than just saying don't to this. What's the harm in trying to use the same options, as system that does work, when your system doesn't?

All in all, you posts were completely unhelpful!

Posted: **Fri Feb 10, 2023 11:05 pm**

I believe the main problem is not using sudo with the init.d script.

The init d script adds some flags, the client daemonizes and adds more flags when the child is exec’d. If you’re actually using systemd, you likely won’t see all of this, as a normal systemd service does not daemonize.

Posted: **Fri Feb 10, 2023 11:08 pm**

The flags were almost certainly not in config.xml.

Also, the client removes options that are equal to default when it writes config.xml.

Posted: **Fri Feb 10, 2023 11:26 pm**

Sorry. I see the options are in config.xml
Edit: well, maybe. I can’t remember if the client presents command line options as part of the config.

I can be more helpful when I’m back to my computer.

But wouldn't it fail to run, rather than running, but failing to fold?

Your probably right about this, but it really should have been installed as a service, rather then being run from the command line.

In my system none of the Args options are in my confix.xml file. They are only able to be changed via Configure in FAH Control.

And, I'm at my computer comparing everything to my Pi's System Info and config files.

Posted: **Fri Feb 10, 2023 11:38 pm**

It would start and daemonize, then the child would fail because it doesn’t have permission to change files owned by user “fahclient”.

Think Ubuntu 22 doesn’t support init.d. In any case the installed ini.d script has been malfunctioning for some time. Things like no pid file, running as root.

Posted: **Fri Feb 10, 2023 11:41 pm**

It’s supposed to be a service, but it is not auto starting at boot for some people. It’s not going to be fixed. All effort is on v8.

Posted: **Fri Feb 10, 2023 11:50 pm**

Anyone willing to be a beta tester is encouraged to try the v8 open beta.
