apt update error in kali

gistfile1.txt

Problem (in my case Kali 2023.2)

└─# apt update

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://kali.download/kali kali-rolling InRelease: At least one invalid signature was encountered.
W: Failed to fetch http://http.kali.org/kali/dists/kali-rolling/InRelease  At least one invalid signature was encountered.
W: Some index files failed to download. They have been ignored, or old ones used instead.

Also error in shell script:
└─# apt-key list                                                                  
create_gpg_home:trap:14: undefined signal: ABRT


FIX:


Edit /usr/bin/apt-key
and comment/change line 78:
  trap "${CURRENTTRAP}" 0 HUP INT QUIT ILL ABRT FPE SEGV PIPE TERM
to:
    #trap "${CURRENTTRAP}" 0 HUP INT QUIT ILL ABRT FPE SEGV PIPE TERM

Try to apt update again.

Thanks mate, you saved my day. Any idea why the ABRT is triggered?
