Comment 54 for bug 1754294

We are in the process of migrating our Apache web servers from 14.04 to 18.04. Seems this will be impossible since the libcurl problem makes Shibboleth authentication in Apache non-existent.

All of the dependencies are Universe packages (not 3rd party). Essentially, anyone wanting SAML2 SSO access controls in Apache has to fall back to 16.04. Bionic is effectively broken.
