I spun up a new instance of Ubuntu and it installed fine.

Thanks for your help.

How much resources has that VM, how much RAM?

The VM has 4GB RAM. I run the Iris CE docker container on a Docker VM with 2GB or RAM so I would have thought 4GB of RAM would be adequate on the stand-alone VM.

Yes, this should be enough. But it does not get enough memory, what will show command?

Hmmm. 3365 available but only 178 free?

so, I run:

sync; echo 1 > /proc/sys/vm/drop_caches

Then:

total used free shared buff/cache available
Mem: 3936 301 3414 6 220 3401

Then:

/tmp/iriskit/IRIS_Community-2021.1.0.215.0-lnxubuntux64/irisinstall

Still results in:

could you check shared memory limits?
it should not be an issue, if it's by default, but just to be sure

Hello Garin,

Differing free vs available memory is a natural occurrence for Linux. The buff/cache is what's being used by the OS for memory and can be relinquished to applications as necessary.

I would check underlying items like OS logs and whether the OS version is supported. error 22 is presumably error 22 invalid argument - not sure what exactly that indicates though.
