My language settings says I have a lot of English variants installed: English (United States), English, English (Australia), English (Canada), etc, etc. But I have no need for these other Englishes, only "English (United States)".
This causes me a lot of trouble, since depending on what program I'm using, the spell checker will tell me that I'm spelling things incorrectly because I'm using American instead of British spelling, and my language preferences in this respect don't seem to be sticking.
Also, every time I open my language settings, I'm warned that "The langauge support is not installed completely," that "Some translations or writing aids available for your chosen languages are not installed yet." It lists these as the packages that I need to install:
libreoffice-l10n-en-za thunderbird-locale-en-gb mythes-en-au libreoffice-l10n-en-gb libreoffice-help-en-gb hunspell-en-ca
Yet at no point did I choose New Zealand English or Canadian English as my chosen languages. Why would I need a spellchecker for Canadian English? I don't get it.
