[DSE-Dev] Bug#980270: python3-setools: needs newer dependencies

[Russell Coker]

Package: python3-setools
Version: 4.3.0-1.1+b1
Severity: normal

# sesearch -A -s httpd_t -d httpd_sys_content_t

The above happens on a system that hasn't had a full dist-upgrade, just
upgrades of selected packages and their dependencies.

Firstly the package depends on libsepol1 (>= 2.9), if that was even possible
to install it probably wouldn't work.  Changing the dependencies to the latest
version of the SE Linux libraries every time is probably the best strategy.

It turns out that having python3-networkx version 2.2-1 installed (significantly
newer than the version 2.0 that python3-setools depends on) caused the problem.
Upgrading python3-networkx to 2.5+ds-2 made sesearch work correctly.
