What does ssh key transfer look like?

Question

SSH

In general, you need to access the server from your home PC.
I copied the ssh keys from my work PC to a flash drive, on my home PC I simply deleted the ssh keys and replaced them with new ones.
But something the server does not let me in "Agent admitted failure to sign using the key."
The question is, what is the correct algorithm of actions? I apparently did something wrong.
