Comment 17 for bug 1970521

I can confirm that boinc-client from jammy-proposed has fixed the bug for me.

Test done:

Start a Jammy vm with "-cpu Conroe-v1".
Confirm from lscpu that avx is not present in Flags.

$ lscpu | grep Flags
Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm constant_tsc rep_good nopl cpuid

install boinc-client

execute boinc and confirm it crashes

Add jammy-proposed to apt sources
update boinc-client from jammy-proposed

execute boinc again and cofirm it did not crash.

Test result: the issue with boinc-client has been fixed.

Package tested:

$ apt-cache policy boinc-client
