I accidentally installed Canadian English instead of US English when I did my install. How can I set this back?
When I go to System Settings > Language Support English and English (Canada) are available, but English (United States), along with all other English variants, are greyed out.
"Install/Remove Languages" below does not have the granularity lower than English, so I can't select a country. How can I install US English?
OK, I ended up doing this a different way.
First I googled around for the file where this setting is stored:
sudo nano /etc/default/locale
Then there were a bunch of '_CA' below that I changed to '_US' like so and everything worked.
And then USA #1.
Under Settings>Language Support just drag the greyed out English (United States) to the top, with plain English under that. This will activate the US locale. You may need to check the Regional settings tab as well.
