Thanks for the answer!
doh-cli is an application with a private Python module.
The doh-cli/0.8-3 release was built to fix Lintian warnings[1].
* control: I need help fixing package-installs-legacy-python-egg-info[2]
The current solution is to remove the directory .egg-info from the
package, but this breaks ${python3:Depends}.
execute_after_dh_auto_install:
rm -rf debian/doh-cli/usr/share/doh-cli/*.egg-info
Alternatively, I may not fix warning
package-installs-legacy-python-egg-info[2].
