Hi,  
I like to test a a golang based producer and I used the example code from [solace-samples-go/patterns/hello\_world.go at main · SolaceSamples/solace-samples-go · GitHub](https://github.com/SolaceSamples/solace-samples-go/blob/main/patterns/hello_world.go) \>  
I got the credentials generate from solace and also downloaded and referred the truststore pem file.  
When I start the program on an uptodate Ubuntu server I get the following error message.  
go run main.go

> 2022/12/09 15:07:03 log.go:41: ERROR solClientDL.c:374&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7f103d8d1640) Could not load library ‘libcrypto.so’, error: /tmp/go-build1430335048/b001/exe/libcrypto.so: cannot open shared object file: No such file or directory  
> panic: an error occurred while connecting: Could not load library ‘libcrypto.so’, error: /tmp/go-build1430335048/b001/exe/libcrypto.so: cannot open shared object file: No such file or directory  
> goroutine 1 [running]:  
> main.main()  
> /…/main.go:47 +0x857  
> exit status 2

I did a basic research on google but didn’t find a solution.

Hey @ulrich - I chatted with my colleague @mcardy and he mentioned that you’ll need to install openssl a simple apt install libssl-dev should fix your issue.
