Lintian noticed that OTPasswd seems to be linked with OpenSSL. If this is accurate, can you extend the license to allow for explicit linkage with that lib?
Here's the error in its entirety: E: otpasswd: possible-gpl-code-linked-with-openssl
N: N: This package appears to be covered by the GNU GPL but depends on the N: OpenSSL libssl package and does not mention a license exemption or N: exception for OpenSSL in its copyright file. The GPL (including version
N: 3) is incompatible with some terms of the OpenSSL license, and therefore N: Debian does not allow GPL-licensed code linked with OpenSSL libraries N: unless there is a license exception explicitly permitting this.
