Lost Custom Context module

I just went through all the upgrades, got all the way to version 12. Had tons of errors on the status screen and went through and resolved them all except the error for the Custom Context module. The error on the status screen said it wasn’t signed and should re-downloaded. I turned it off, back on, thought I uninstalled it, eventually removed it from the system.

Now, I tried to go back into the modules admin and re-install it but I can get it to show up anymore. Where did it go? Shouldn’t it come up when I click “Check Online” with all the repos selected at the top?

Thanks in advance for any help.
