Bug#969064: apr-util: Cannot fulfill the build dependencies

[Aurelien Jarno]

Source: apr-util
Version: 1.6.1-4
Severity: serious
Tags: ftbfs

The following packages have unmet dependencies:
 python : PreDepends: python-minimal (= 2.7.17-2) but it is not going to be 
installed
          Depends: libpython-stdlib (= 2.7.17-2) but it is not going to be 
installed
          Depends: python2 (= 2.7.17-2) but it is not going to be installed

IIUC the package should either:
- switch to python3
- build-depend on python2 instead of python
