There is an updated pull request by newbluemoon against master on the void-packages repository https://github.com/newbluemoon/void-packages po4a https://github.com/void-linux/void-packages/pull/34029 po4a: update to 0.65 Two sgml tests fail because they invoke `onsgmls` from OpenSP to verify a test sgml file against a docbook DTD which errors out. The `opensp` package adds a sgml catalog entry `CATALOG /usr/share/OpenSP/catalog` and in `/usr/share/OpenSP/catalog` there is a sgml declaration: `SGMLDECL unicode.sd` When this line or the catalog entry above is removed `onsgmls` falls back to its default definition and succeeds and all tests are passed. I’m not sure if the problem is related to Void’s `opensp` package or to `po4a`. Any ideas are welcome! :) I also asked upstream: https://github.com/mquinson/po4a/issues/327 #### Testing the changes - I tested the changes in this PR: **NO** A patch file from https://github.com/void-linux/void-packages/pull/34029.patch is attached
