I built i386 packages without endbr and uploaded everything to https://people.debian.org/~bigeasy/openssl-3-noendbr/ Could you please give a try report if this is correct? Sebastian Yes, with libssl3_3.0.3-4.noendbr_i386.deb this is fixed. Thanks -- Wolfgang Walter Studentenwerk München Anstalt des öffentlichen Rechts
