Install Client on Linux 18.04

I followed the installation instructions here: https://github.com/corrados/jamulus/blob/master/INSTALL.md

After install. executing the ./Jamulus command I am getting the following:

/opt/Jamulus$ ./Jamulus
Gtk-Message: 11:11:39.148: Failed to load module "canberra-gtk-module"
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel

jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock

I am far from a Linux expert so any help would be great!

I have run Jamulus, but get this on startup:

Cannot lock down 82280346 byte memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/5)(1: Operation not permitted)
JackClient::AcquireSelfRealTime error
libpng warning: iCCP: known incorrect sRGB profile

should I use "sudo ./Jamulus" ??
Thanks!

Also, now getting:

Opening in existing browser session.
[0918/120149.837613:ERROR:nacl_helper_linux.cc(308)] NaCl helper process running without a sandbox!
Most likely you need to configure your SUID sandbox correctly

hmm...
