Okay, this makes sense. It wasn't clear to me if the soname bump mentioned in the bug report was relative to jessie or to what's in the archive. > Ubuntu have a patch for this, which I have attached. The lintian > overrides are unnecessary in Debian (lintian has been changed to > accept the v5 suffix as valid). This patch replaces libginac5. This is in line with what the bug report says: "Rename the library package, append "v5" to the name of the package (e.g. libfoo2 -> libfoo2v5)". I can do that and will do so ASAP if it's the right thing to do. But don't the two packages have to coexist? (After all, one of the concerns is to not break packages which are not in the archive!) (Sorry, I also found the wiki explanation vague on this point. Maybe, somebody can improve it.) -richard.
