I was very confused for a bit, because the id seems fine. So I think lintian diagnostic here is very confusing. The problem is that the alternative dependency syntax is invalid. It should be something like: | libmpathpersist-internal-symbols-invalid #MINVER# When installing that package, dpkg-shlibdeps would produce something similar to the following warning+error: dpkg-shlibdeps: warning: can't parse dependency libmd.so.0 libmd-invalid (>= 0.0.0) dpkg-shlibdeps: error: invalid dependency got generated: libmd.so.0 libmd-invalid (>= 0.0.0), libc6 (>= 2.34), libmd0 (>= 0.0.0) But that's certainly too late, and having to inflict this kind of breakage on the archive to be able to notice the mistake is not a nice thing for the tool to be doing. I guess the problem is that the template is not a valid dependency, so it will be tricky to verify at that time, but I guess the parser could be made more strict in any case. Will see how to improve this. Thanks, for the report! Regards, Guillem
