[Debichem-devel] Bug#999767: rdkit: FTBFS on buildds / reproducible builds without network access

[Aurelien Jarno]

Source: rdkit
Version: 202103.5-1
Severity: serious
Tags: ftbfs
Justification: Policy 4.9

According to Debian Policy 4.9:

| For packages in the main archive, required targets must not attempt
| network access, except, via the loopback interface, to services on the
| build host that have been started by the build.


However rdkit tries to download fonts from google.com during the
configure stage, leading to a build failure when network is not
available:
