Minimal requirement for GPG ?

Hi,

We are using pass to handle some shared secrets in my team, but on one
laptop, with GPG 1.4.16, the gpg file is crypted only with the first key in
.gpg-id. Is there a limitation on this old version of GPG ? I did not find
any information about pass requirement.

*gpg2 --batch --list-packets ~/ipsec.gpg *

> gpg: encrypted with 4096-bit RSA key, ID xxx, created 2017-04-03

> gpg: decryption failed: No secret key

The correct file, with all my collegues and myself, created on another
workstation, with GPG 2.2.4
