percona-xtrabackup for Ubuntu
-----------------------------

The percona-xtrabackup base packagehas a hard dependency on boost 1.59.0,
which is older than the current system version in Ubuntu Bionic. The base
package downloads boost 1.59.0 during the package build, which is something
that can't be done on Launchpad builders when building the Ubuntu package.

Alternatively, for Ubuntu, boost 1.59.0 is included under the boost directory
in the percona-xtrabackup package.

To repack the percona-xtrabackup_*.orig.tar.gz that uscan will download run:

  ./debian/rules refresh-boost

this will wget to retrieve the boost tar file from:

  http://jenkins.percona.com/downloads/boost/boost_1_59_0.tar.gz

and bundle the code into percona-xtrabackup_*.orig.tar.xz.
