[SR-Users] RTPENGINE question

[Andrew Chen]

Sorry let me clarify this line here:

"...at the time, I was running an older version 8.0.x so I recompiled all
the ngcp packages under this kernel and completed the installation without
issues.."

8.0.x is the older ngcp version. I recompiled version 9.0.1.0 under that
new kernel version 5.3.0-1035-aws #37-Ubuntu
