similar to #509980: https://api.gentoo.org/overlays/repositories.xml "error on line 489 at column 10: Opening and ending tag mismatch: source line 0 and repo"
from the layman command: * Failed to fetch overlay list! * Original Error was: Failed to parse the overlays list fetched from http://www.gentoo.org/proj/en/overlays/repositories.xml * This means that the downloaded file is somehow corrupt or there was a problem with the webserver. Check the content of the file. Error was: * mismatched tag: line 489, column 4
Looks like missing slash. Fix pushed, will propagate in a few hours.
