Hello,

When I try to run it on my linux mint

uname -a
Linux beta7 5.4.0-205-generic #225-Ubuntu SMP Fri Jan 10 22:23:35 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

I got this error [1] 43552 illegal hardware instruction (core dumped) ./Msty_x86_64_amd64.AppImage
There is no difference use I AppImage or deb package, get same error
There is from dmesg output

[ 1812.385094] traps: msty[43552] trap invalid opcode ip:7f216ca5b5bc sp:7fff4cca0060 error:0 in index.node[7f216c89a000+2549000]

cpu is i7-3770 x64

how can I fix it?

@romainrossi commented on GitHub (Mar 16, 2025):

Hello,
I got the same error on Ubuntu 20.04 :

$ msty
Illegal instruction (core dumped)

kernel :

$ uname -a
Linux vault15 6.8.0-52-generic #53~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jan 15 19:18:46 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

In the dmesg log :

msty[80050] trap invalid opcode ip:7afdd76d05bc sp:7fff3fc5aff0 error:0 in index.node[7afdd750f000+2549000]

I have Msty running fine on another computer, with the exact same OS, but more recent hardware. I suspect the error to be related to supported CPU instructions so here is my CPU info (4 cores, only first is shown) :

$ cat /proc/cpuinfo

Thank you for any hint on how to solve this (maybe build from source with specific build configuration ?).

this is really poor user experience to force them to use the god awful discord service instead of Github issues like it's meant to be

You can send an email as well so really not forcing. I'm suggesting Discord because we are always there and responding is faster. And, yes, not everyone is on Discord, I understand but similarly not everyone is on GitHub as well. I'm just saying that this is for docs and we don't monitor this for issues (the notifications from GitHub just gets filtered out in our inbox; we receive too many of them).
