About --- in Mar 2024 began the time64 transition in Sid & trixie (testing). Same changes were made in Ubuntu Noble, while Jammy was unchanged by t64. First thing I did was convert all my debian/control to ng form where, for example, libxen-4.18 went to libxenmisc4.18. All of the Debian/Ubuntu builds went to ng packaging. However, not all builds went to t64, like Bookworm & Jammy did not. $ grep Package: t64-delta-Mar24-ng -Package: libxenmisc4.18 +Package: libxenmisc4.18t64 -Package: libxenstore4.0 +Package: libxenstore4.0t64 -Package: libxentoolcore1 +Package: libxentoolcore1t64 -Package: libxenfsutl4.18 +Package: libxenfsutl4.18t64 as seen from above, 4 libraries are renamed for t64. Similar changes, more predictable, are found in debian/rules.real author --- PryMar56 Feb 2025
