This also breaks Shibboleth since libapache2-mod-shib2 has a dependency on libxmltooling7 which depends on libcurl3.

If installing libcurl3 alongside libcurl4 was possible this wouldn't be an issue. Why is this not a high priority? It makes 18.04 unstable at best. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754294 Title: After last updated libcurl3 on libcurl4, some apps are removed.
