[dgaastra]

Describe the bug Debian Install Fails: trap invalid opcode ip:564902a7cbc8 sp:7ffce9909b80 error:0

To Reproduce Steps to reproduce the behavior: [cat /etc/debian_version -> 11.7]

   cd /tmp
    wget https://dragonflydb.gateway.scarf.sh/1.3.0/dragonfly_amd64.deb
    sudo dpkg -i dragonfly_amd64.deb

Expected behavior DragonFlyDB to launch successfully.

**Environment (please complete the following information):**
Debian 11.7 - with Redis installed and stopped

Additional context There are no instructions to be found for - could you please provide those: [1] How to install DragonFlyDB on Debian as a service - So just performed the standard dpkg installation [2] How to run DragonFlyDB as a unix socket?

Thanks so kindly Dennis

Hi @dgaastra Can you please paste here the output of simply running

/usr/bin/dragonfly --alsologtostderr

Let's see if it gives us some more info

[dgaastra]

sudo /usr/bin/dragonfly --alsologtostderr

Gotcha, that's not adding much :)

Can you also please paste the outputs of cat /proc/cpuinfo and uname -a?

[chakaz]

It might be that because your CPU does not support avx/avx2 you can't run Dragonfly. You could try to build it locally without avx (via cmake ENABLE_AVX=OFF), although I've never tried it myself, so it might not be a smooth path.

[romange]

@chakaz - it's not just AVX, Dragonfly requires at least sandybridge processor architecture for x86_64

[dgaastra]

Yes; I can confirm that moving the VM to a "Intel(R) Core(TM) i5-8500B CPU @ 3.00GHz" made it work. Now my question is how to setup a unix socket with DragonFlyDB, like: unixsocket /var/run/redis/redis-server.sock unixsocketperm 766
