Hi, I think the following change might be the relevant one:
--- a/update-ca-certificates +++ b/update-ca-certificates @@ -164,8 +164,6 @@ done fi -rm -f "$CERTBUNDLE" - ADDED_CNT=$(wc -l < "$ADDED") REMOVED_CNT=$(wc -l < "$REMOVED") It triggers this stderr output during openssl rehash (l. 184): rehash: warning: skipping ca-certificates.crt,it does not contain exactly one certificate or CRL I'm happy to change the upstream integration test to adopt to that, or else it would also make sense to me that update-ca-certificates not output to stderr under normal operation. Perhaps it might even make sense to suppress this particular message entirely? Kind regards, Benjamin
