Help using the apt command

I have been really enjoying Parrot OS on my laptop so far! The only thing I can’t figure out is the apt command. It tells me there’s an upgradable package, but I can’t figure out how to actually upgrade it. See the commands I ran below. Any help or advice would be greatly appreciated, thanks!

Before this, I was having a lot of issues with deb.parrot.sh returning 404 errors. Eventually, I might try wiping my laptops harddrive, downloading Parrot, putting it on a USB stick, and doing a fresh install. I’ll see if that fixes things. It’s on my to do list to read more about Debian’s apt package manage, and be able to fix these issues myself! Until then… the ultimate “have you tried turning it off and on again”: doing a fresh install with a fresh installation ISO!

I have the 404 errors whether I use apt, apt-get, or parrot-upgrade… and when i use the synaptic package manager.

My work around thus far is keep running the same upgrade command until all the upgrades are downloaded and installed. Takes about 10 to 15 times but it eventually completes.

I’ve been having this happen since the Parrort-4.11.2 upgrade
