404 error - failed to download/install imagemagick

[FlyingTomahawk]

RPi Zero 1.3
RetroPie 4.1
PSU 1A
WiFi dongle

I am trying to get the custom script of @meleu running but I need to get imagemagick first.
So I type sudo apt-get install imagemagick and it preps for the install.
It asks me if I want to continue and I enter "Y".
Then when it should connect to the server to download imagemagick I get a whole bunch of 404 errors.

E: failed to fetch "...long URL..." 404 Not found [IP: 5.153.225.207 80]

Does anyone else has that issue at the moment or is it something on my end?

I can connect via FTP and Putty to my RPi Zero thanks to the WiFi dongle so I don't think that it is a internet connection issue. Few days ago I did the same procedure on my RPi 3

@FlyingTomahawk you didn't update package list first. sudo apt-get update

@BuZz

Thank you for your quick reply BuZz!
Man I feel so stupid at the end after the 404 error messages it says run apt-get update or --fix-mis
Duh! I was stupid enough to type apt-get update without the sudo command and that didn't work of course.

Now it is downloading the updates and all seems to go well. Thanks again for the quick help.
I really need to get this whole Linux command stuff into my head asap.
