trying to make space for some updates, i accidentally deleted some linux files. oops.

when I run

sudo apt --fix-broken install

I see

That particular version doesn't seem to exist anymore, it was updated to 4.15.0-52.56
Is there something wrong with

sudo apt update
post back the results.

603 packages can be upgraded. Run 'apt list --upgradable' to see them.

603 packages is a lot. so
$apt list --upgradable | grep linux-headers
linux-headers-generic/bionic-updates,bionic-security 4.15.0.74.76 i386 [upgradable from: 4.15.0.46.48]

so I went ahead and tried again.
christopher@fern:~$ sudo apt --fix-broken install

this time I got no error fixing those missing deps.

why is that? is it because apt update tells --fix-broken to get the most up-to-date version of those image and header files?

sudo apt update refreshes the package list on your machine by grabbing the latest listings from the archives.
Always run it before running any other apt commands.

So, what did you actually delete...
