Package: isync Version: 1.4.4-3 Severity: important Hi,
isync (mbsync binary) is GPL-2+ licensed and depends on libsasl2-2, which is licensed under CMU's BSD-4-clause license and covered by the RSA-MD and OpenSSL licenses. All of them have an advertisement clause in place, which is known to be incompatible with GPL. There are several possible solutions to this problem:
1) Build without SASL support. It is optional. 2) Support my request at #996892. 3) Ask upstream to add a license exception for libsasl2-2, similar to the one that was required by Debian for OpenSSL for a long time. 4) Port to gsasl or another compatible SASL implementation. Thanks for your consideration, Bastian
