I have gone into the Update settings and changed mirrors to a few closer to me that showed as, "fast", but still get, "Checking for updates, please wait..." and nothing happens. I have waited a long time to see if it works but it only shows the message above. So far 2 US mirrors (including kernel) and one CDN don't help.

/etc/apt/sources.list contains:

## Generated by deepin-installer-reborn
deb [by-hash=force] http://packages.deepin.com/deepin unstable main contrib non-free
#deb-src http://packages.deepin.com/deepin unstable main contrib non-free


Sorry, but I couldn't determine how to change the 3 lines above to show as a code block.

Any tips to get updates working? I know that sudo apt-get update && apt-get upgrade would work, but I woud like it to work fom the settings on the desktop.
