Instead of 'contrib' and 'non-free' you can better use 'restricted' and 'universe' in case of L4T...I have the 4GB model working now at SiDock, but it was quite a struggle to get all 32-bit libraries.

BTW: I received Universe WUs for the 4GB model over the last three days (1, 2 and 3 February 2024). Not many but it might be a sign that the 'dry spell' will not last forever.

First things first!

First step 1: sudo dpkg --add-architecture armfh

Then step 2: sudo apt update --fix-missing

only thereafter can you do

Step 3: sudo apt install libc6:armhf libstdc++6:armhf zlib1g:armhf libfuse2:armhf libgomp1:armhf libboinc7:armhf

I myself am presently re-doing these steps as my fallback project -SiDock@Home- has stiffer requirements and my 4GB Nano seems to be missing libgomp1:armhf.

My 2GB model can't even run SiDock: its 18.04 L4T has glibc 2.27, too low for SiDock

Still no luck with your suggestions.
Endless list of errors saying "skipping acquire of of configured file" "inrelease doesn't have the component 'contrib' and component 'non-free' check spelling
InRelease' doesn't support architecture 'armhf'


Bizar. I have my Jetson Xavier NX working now too with the exact same approach -and the exact same error messages in the beginning. Try rebooting between the steps.


The errors point to having just 'main' is the sources. Either you haven't edited those two lines, or you edited 'starred-out' lines -having no effect.
Do all as I suggested, verbatim, and in the right sequence.

If you don't trust it: take out your SD card, put in a new one with the latest jetpack image for the Jetson Nano or TX and try with that.
If all works well, think about running the Jetson straight from SSD via USB 3.0

I would have liked to get my Jetson SoC's running on Universe but alas there are no 32 bit libraries available in the Nvidia L4T distros. I could change them over to a normal Linux distro like Ubuntu but I would lose the standard Nvidia CUDA development installation that allows me to use the Nvidia gpus at Einstein where they are quite productive.


Both my Jetsons crunch Universe and run L4T (the 4GB model upgraded to 20.04.6 LTS with Glibc 2.31). I got some warnings installing 32-bit libraries, but it is workable.
The 2GB model even has a both OpenCL and CUDA capable GPU, but still runs on 18.04.6 LTS and has Glibc 2.27

Where did you find the 32bit libraries in L4T?
I have a Nano 4GB original and a 4GB TX2-NX both running the L4T based on 18.04.6 LTS and I just get messages that any 32bit library is unavailable in the distro.


My guess is that when you check your sources list (/etc/apt/sources.list.d/nvidia-l4t-apt-source.list) that you see
deb https://repo.download.nvidia.com/jetson/common r32.4 main
deb https://repo.download.nvidia.com/jetson/t210 r32.4 main


edit that (as super user/with root access) so it looks like
deb https://repo.download.nvidia.com/jetson/common r32.4 main contrib non-free
deb https://repo.download.nvidia.com/jetson/t210 r32.4 main contrib non-free


then do a 
sudo apt update --fix-missing
sudo apt dist-upgrade


then do a 
sudo dpkg --add-architecture armhf
sudo apt update --fix-missing
sudo apt install libc6:armhf libstdc++6:armhf zlib1g:armhf libfuse2:armhf libgomp1:armhf libboinc7:armhf


to be really sure you get all 32-bit apps from all projects, edit you cc_config.xml to have both these lines
<cc_config>
    <options>
        <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
        <alt_platform>armv7l-unknown-linux-gnueabihf</alt_platform>
    </options>
</cc_config>


If you want work for projects that have real old apps, you can also add a third line:
<alt_platform>armv6l-unknown-linux-gnueabihf</alt_platform>

No Boinc update

You need to update BOINC Manager as old versions are compiled with expired certificates.


By the looks of it, his problems are with his i7 system that has the latest version of BOINC....

I have a 32-bit ASUS Tinkerboard (RK3288), cooled with an 52Pi Ice Tower low profile cooler, that manages between 7,800 and 9,100 credits/day for Universe@Home, running 24/7 on all cores.
I also have an Odroid-XU4 that manages the same daily scores, this while doing SiDock@Home on the side. It is cooled with a Xigmatek N881 Porter and 80mm Noctua NF-A8 5V fan.
My best scoring ARM system presently is a 8GB Odroid-M1, recently converted to be able to run 32-bit tasks by adding the 32-bit libraries to its 64-bit Debian Bookworm
It is still climbing in its daily scores and is almost at the 9,000 daily credits and needs no additional cooling due to its huge heatsink.

hello everyone!
For the past two days I have noticed that neither BoincStats or Free-DC are showing I have contributed any credits to Universe@home. I can see I have active tasks running on my machines and Universe@Home is showing my total credit count increasing throughout the day. Has anyone else noticed a similar trend? My other projects seem to be updating as normal (MilkyWay, Einstein).
I did have something similar happen with Einstein where I had to consent to them exporting my stats but I can't seem to find anything similar for Universe@home under my preferences (it had something to do with GDPR Compliance in the US).

Thanks for your help everyone!


I see it too on both stats sites, and additionally on https://signature.statseb.fr/next_badges.py

As the Orange Pi with H5 SOC only has 1GB of RAM, why do you use a 64-bit OS? If you install a 32-bit OS it should work, just like your Raspberry Pi.
But there may be more to it, as my Raspberry Pi 4 (with 4GB of RAM and with 64-bit kernel) does have work.

There's something amiss with the time estimate of the new Universe QuarkStars v0.03 WU's, I have a two that keep getting closer to the 100.0%%, but ever so slower it seems.
Another (Universe Ultraviolet reionization v0.05) exceeded the disk limit (not only with me, with my wing men as well).

Hi, I see on my account page that I have a badge. It has in the meantime changed from a grey one to a blue one. What does this signify? Are these RAC badges or Milestone badges? What are the levels that can be scored?
