I tried Putting Acquire::By-Hash "force"; to /etc/apt/apt.conf.d/51acquire_by_hash Changing […]

For context, I am a self-taught developer, and I picked up Cloud operations along the way. I gained the interest on Performance, so I picked up the book "Systems Performance" by Brendan Gregg. In the book, there is a case study about slow disks. It appears that the "disk utilization" is at 80%. I’m trying […]
