Hexos Applications in TrueNAS keeps crashing

[duonguyen]

Hi, since the new HexOS update, I can't use the deck, server is still there, TrueNAS still accessible. I've unclaim and reclaim the server, but it's stuck on waiting for connection and will fail.

HexOS now appears in the Applications tab on TrueNAS but will periodically try to start and then crash after running for a second, and there appears to be an update available. 

Thanks in advance for you help!

Still broken for me.

I am getting the same issue and I just had to do a full reinstall.

I have the same issue, the app try's to start serveral times, but fails.
Same Version and App Version.

Question for any of you affected by this issue, are you running HexOS in a VM or on a really old CPU?  HexOS Local, which is now a requirement of HexOS, requires the AVX and SSE4.2 instruction set on your processor to function.  Pretty much all modern CPUs released since 2011 have these instruction sets (there may be a few outliers that I'm unaware of), so either you are all running on really really old hardware, or you're running in a VM that is not exposing those instruction sets with the CPU model.  If a VM, you can change the CPU model to "host-passthrough" or simply something that supports these instruction sets.

I guess my AMD Phenom(tm) II X6 1055T Processor is too old and will need to update my motherboard cpu

Yup.  Unfortunately one of the packages that HexOS local depends on (bun) requires these CPU features (for now at least).

@jonpim having the same problem but on an AMD Ryzen 5 3600, no vm

for some reason deck.hexos keeps saying "failed shutdown" & "no storage pools found"

[jonp]

Hmm...

@mill3000 can you connect with him on this issue?

I have the issue since the latest truenas update (25.10.3) on an i5-7500. I have not tried to unclaim/claim, but rolling back back TN to 25.10.2.1 did not work.

My machine is an HP ProDesk 600 G3 SFF i5-7500.

Yes that processor does not meet the minimum specs unfortunately.

@Maximus do you have time to do a Google meet tomorrow? We are in the CST. Can you send me over sometimes that would work for you and we can set up the appointment.

@da.rencan you also send me some times for tomorrow? Again in CST that we can do a Google meet?
