app-crypt/dehydrated-0.7.1 started failing with output: Warning: Will read cert request from stdin since no -in option is given + Requesting new certificate order from CA... + ERROR: An error occurred while sending post-request to https://acme-v02.api.letsencrypt.org/acme/new-order (Status 400) The problem is because the behavior of "openssl req -verify" changed in openssl >= 3.2.0. It was reported in the dehydrated github: https://github.com/dehydrated-io/dehydrated/issues/924 https://github.com/dehydrated-io/dehydrated/pull/923 and fixed with this commit: https://github.com/dehydrated-io/dehydrated/commit/4fd777e87e589652b1127b79ac6688ed7cb151fe That commit was almost a year ago and there hasn't been a release of dehydrated since then. Please add the fix as a patch in the 0.7.1 ebuild. Thanks. Reproducible: Always
