tlmgr: not verified: valid signature with expired key

[Georg-Johann Lay]

Hi,

I am having trouble with installing the listofitems package
and need support how to fix the following issue:

$ sudo tlmgr install listofitems
tlmgr: package repository https://ftp.fau.de/ctan/systems/texlive/tlnet 
(not verified: valid signature with expired key)
[1/1, ??:??/??:??] install: listofitems [792k]

Using:

This is pdfTeX, Version 3.141592653-2.6-1.40.24 (TeX Live 2022) 
(preloaded format=pdflatex 2023.2.28)  7 MAY 2024 09:07

I already asked the package maintainer, and he says that it's
a TexLive issue and not a problem with listofitems itself.

Thanks in advance,

Johann
