Hi Sylvestre,

there is no lldb-server-6.0 in that directory, but that hint was correct:
$ sudo ln -s /usr/lib/llvm-6.0/bin/lldb-server 
/usr/lib/llvm-6.0/bin/lldb-server-6.0.0
$ ls -l /usr/lib/llvm-6.0/bin/lldb-server*
-rwxr-xr-x 1 root root 6920288 Sep 11 22:27 
/usr/lib/llvm-6.0/bin/lldb-server
lrwxrwxrwx 1 root root      33 Nov 18 09:28 
/usr/lib/llvm-6.0/bin/lldb-server-6.0.0 -> /usr/lib/llvm-6.0/bin/lldb-server

That seems to fix it!
Thanks,
