From T157744#3025326 (how meta!):
> PyICU requires the underlying C++ library to work, and this is in the libicu52 apt package on Debian Jessie. When this is installed, PyICU can then be installed in a virtualenv. Alternatively, the python-pyicu apt package can be installed, which installs PyICU and the underlying C++ library systemwide. One of the above packages would need to be installed in the python 2 Docker image to be used in Kubernetes containers.
Original request: icu is used for unicode-string list handling/sorting (http://www.linuxfromscratch.org/blfs/view/cvs/general/icu.html).
The discussion has shifted to why the following traceback shows up (despite debugging steps referenced throughout the task):
```
