Getting this error on a couple machines one Ubuntu 16.04 the other 18.04
./t-rex: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by ./t-rex)
I'm guessing libcurl3 package isn't up to date, at least on 16.04. Could you contact me via direct messages please? We'll try to investigate this issue. I can't send you a direct message because of the default bitcointalk policy not to accept them from newbies.
