I've been trying to install docker on my WSL and it is constantly throwing an error

I've tried sudo apt-get remove ec2-instance-connect and it is throwing this error:

It is not allowing me to run an upgrade or install any new packages.

Can anyone help me here?

I just ran across someone else with pretty much the same issue on the Unix & Linux Stack. When looking for an answer, I just found this (unanswered) question. I posted an answer there, but I'll repeat the relevant parts for this question in case anyone else comes across it.

ec2-instance-connect turns out to be a pretty problematic package if installed erroneously on WSL. It should typically only be installed on Ubuntu when running in an Amazon/AWS EC2 instance.

It has both a post-install and post-remove script that assume Systemd, which isn't available on WSL. As far as I can tell, since the postinstall never completes successfully, it attempts to run every time you do many other apt commands.

To get rid of it (and stop the errors), it's not enough to sudo apt purge ec2-instance-connect, because the post-remove errors will still fail (and the package will remain). You'll need to:

sudo rm /var/lib/dpkg/info/ec2-instance-connect.postrm
sudo apt purge ec2-instance-connect
sudo deluser --system --quiet ec2-instance-connect

apt should be working properly again after this, but please see the Unix & Linux Stack answer linked above for some discussion on other things to check that may need to be cleaned up.
