[ceph-users] Should ceph build against libcurl4 for Ubuntu 18.04 and later?

[Matthew Vernon]

Hi,

The ceph.com ceph luminous packages for Ubuntu Bionic still depend on
libcurl3 (specifically ceph-common, radosgw. librgw2 all depend on
libcurl3 (>= 7.28.0)).

This means that anything that depends on libcurl4 (which is the default
libcurl in bionic) isn't co-installable with ceph. That includes the
"curl" binary itself, which we've been using in a number of our scripts
/ tests / etc. I would expect this to make ceph-test uninstallable on
Bionic also...

...so shouldn't ceph packages for Bionic and later releases be compiled
against libcurl4 (and thus Depend upon it)? The same will apply to the
next Debian release, I expect.

The curl authors claim the API doesn't have any incompatible changes.

Regards,

Matthew

libcurl3 includes a libcurl.so.4 for historical reasons :-( ]

Bionic's mimic packages do seem to depend on libcurl4 already, for what
that's worth:

***@vm-gw-1:/# apt-cache depends ceph-common
ceph-common
...
Depends: libcurl4

We've encountered the same problem on Debian Buster

It looks to me like this could be fixed simply by building the Bionic
packages in a Bionic chroot (ditto Buster); maybe that could be done in
future? Given I think the packaging process is being reviewed anyway at
the moment (hopefully 12.2.10 will be along at some point...)
