OS

Linux archlinux 6.8.9-arch1-2 #1 SMP PREEMPT_DYNAMIC Tue, 07 May 2024 21:35:54 +0000 x86_64 GNU/Linux

angr

angr                          9.2.102

download example from :
https://github.com/N4NU/Reversing-Challenges-List/blob/master/Easy/Codegate_CTF_2018_Preliminary_RedVelvet/RedVelvet.7z my script

import angr

p = angr.Project('./rvpatch')

sm = p.factory.simgr()
sm.explore(find=lambda s: b"HAPPINESS:)\n"*15 in s.posix.dumps(1))

if sm.found[0]:
    print (sm.found[0].posix.dumps(0).replace(b'\x00',b''))

This is not a critical problem, and the script can finish and return normal answer. i think maybe my archlinux missing package since another ubuntu server could finish without it. But I want fix this error and get to know why i got this.

Thank you

Looks like these are actually missing tags from the libc.so.6 on your system, which is, I'm guessing, ubuntu 24.04. You're right that it's harmless but I'll fix it at some point.
