Cannot change from one language format to another for example from English US to English UK in the language tab of language-selector-gnome

[Tony Thuitai]

Ubuntu automatically sets the English US language as the system language for the region that I reside in which mainly the English UK language as one of its official languages but not the English US language. When using the Language Support app to attempt to change the system language and regional formats to English UK, the English UK option is greyed out and cannot be selected in the Languages tab. To properly change the language in Ubuntu, I used the Gnome settings to change the language and the regional formats, restarted the shell, and used the Language Support app to apply the regional formats system-wide so that it can apply to the display manager as well. In Xubuntu or any other official Ubuntu flavour that uses the Ubiquity installer for installation and only uses the gnome language selector for language and region formats selection. Changing from one format of a language to another for example from English US to English UK is not possible graphically with the Language Support app alone because the desired language format, for example, English UK is greyed out and not selectable. The attached screenshot illustrates the issue but in this case, attempting to change from English UK to English US by using the language support app alone to attempt the language change.

Thanks for your report.

Please note that you are supposed to drag the language you want to use to the top of the list, not just click on it. Can you try that and let us know if it works.

[Tony Thuitai (tonythuitai-deactivatedaccount)]

I attempted to drag a language format to the top before the bug report but nothing happened and attempted to drag again recently but it works as long as the green line is visible at the top before releasing the left mouse button. Marked it as invalid. The Language support app's first impression may confuse new users. Marked it as invalid because I am used to selecting a language instead of dragging the language to the top.

[Gunnar Hjalmarsson (gunnarhj)]

Good.

The reason for this solution is to make it possible to enable fallback languages when your desired language is not fully translated. (Can say that you were not the first who made this mistake.)

I understand and the solution is better than the one I am used to.
