[Bug 1770242] Re: Please merge from debian 2.4.33

2018-05-17 Thread Andreas Hasenack
Even in current cosmic this doesn't work:
# apt install apache2 libapache2-mod-shib2 libapache2-mod-md

It's because it tries to pull in libcurl3, and that removes curl
libcurl4 pollinate ubuntu-server.

So to install shib2 and mod-md in cosmic, *before* this upload of 2.4.33, one 
has to:
root@cosmic-apache-fix-migration:~# apt install apache2 libapache2-mod-shib2 
libapache2-mod-md libcurl3

[Bug 1770242] Re: Please merge from debian 2.4.33

2018-05-17 Thread Andreas Hasenack
I'm dropping this because of a complicated chain of dependencies in the
archive. It's even hard to explain, but let's try, so that others who
stumble across this will have some context.


>From excuses:
trying: apache2
skipped: apache2 (0, 56, 7)
got: 15+0: a-8:a-1:a-1:i-1:p-3:s-1
* ppc64el: libapache2-mod-proxy-uwsgi-dbg, libapache2-mod-shib2

IRC discussion started here: https://irclogs.ubuntu.com/2018/05/16
/%23ubuntu-release.html#t16:45

Highlight:
  ahasenack: in cosmic, libapache2-mod-shib2 is installable (though 
not coinstallable with other things)
  ahasenack: in cosmic-proposed, it is not installable because 
apache2-bin now depends on libcurl4 where it did not previously

So apache2-bin now ships a new module called mod-mo
(https://httpd.apache.org/docs/2.4/mod/mod_md.html). This module we (and
debian) have been carrying in the archive as its own source. In the
apache build it links with libcurl4, which is fine and good. But it does
add a libcurl4 dependency to apache2-bin which wasn't there before.

Cue in libapache2-mod-shib2, from the shibboleth-sp2 source. It requires
libxmltooling7, which in the archive is built with libcurl-
openssl1.0-dev that is provided by a special curl3 source linked with
openssl 1.0. That brings in libcurl3, which cannot be coinstalled with
libcurl4. The curl package is a bit weird, because even though it's
called libcurl3, it does not ship libcurl3:

$ apt-file search libcurl.so.
libcurl3: /usr/lib/x86_64-linux-gnu/libcurl.so.4
libcurl3: /usr/lib/x86_64-linux-gnu/libcurl.so.4.5.0
libcurl4: /usr/lib/x86_64-linux-gnu/libcurl.so.4
libcurl4: /usr/lib/x86_64-linux-gnu/libcurl.so.4.5.0

And we have explicit conflicts between libcurl3 and libcurl4.

I don't know how to solve this, so I'm unassigning myself from the bug.
