Hi Guido, I had a look at your mfgtools package (1.2.91+0git6b465-0pureos+librem5.2). Its copyright file only misses libuuu/sparse_format.h's copyright notice and Apache v2 license.
For the current version 1.3.154 there are new files with 2019 or 2020 copyright year and libuuu/buffer.cpp's copyright date changes to 2018-2019. Also, libssl-dev is introduced as a new build dependency. Therefore you should relicense the debian/patches (most of them can be dropped) because GPL-3+ is not compatible with the OpenSSL license. I would appreciate the package to be in Debian and volunteer to co-maintain it if you do not want to maintain it alone. Cheers, Bastian
