Re: sudo apt-get upgrade

sudo apt update
updates the files so :-
sudo apt upgrade -y
will work

just doing upgrade will not work by itself


&& < will only do the following command if the previous one succeeds

Re: Copying to USB HDD is very slow

buffered reads is a red herring

Code: Select all

dd if=/dev/zero of=test bs=524288 count=2048

change test to point to your mounted drive
and give the results

rsync will give various results depending on what it there already etc..

Re: RPI4: Why is everything still 32-bit?

I have no idea why, but every time I attempt to use it, it breaks. It's probably something I'm doing, but I don't know what, and can't track it down because it's such a fundamental part of the system that when it breaks, nothing boots. It's also 'solving' an utterly non-problem for me: booting quic...
