Changing locale on Pinebook Pro

[Perl6_user]

When running the installation process on the new Pinebook Pro, I inadvertently selected the wrong locale, so the desktop is now in Catalan (I think).
What is the simplest process to correct the locale (to English, Canadian or US)?

If I had an installation medium, I'd just re-run the install and pick the right value this time. (Is there some way to do that with the machine as delivered?)
(There's nothing on the system that can't be wiped out and reset.)

If it's possible to change a value in a configuration file (or files), what are the files and values? (I think I can stumble through nano). Please assume a
combination of Unix background and momentary fumbling.

For a simple difficulty, I'd probably try asking the distribution site, but this problem's at the intersection of software and hardware.

(I'm anxious to get the machine usable; what I've seen so far is very attractive.)

You can get an installation medium. But you'll end up in Catalan again. It's not something you did wrong, it's something wrong with the version of Manjaro that ships with the PBP. Once you do an update, the problem will go away. But you'll probably end up in Catalan one more time.

Thanks. That was a good reference.

I am thinking that the PBP (And probably other Pine64 singleboard computers..) could use a utility similar to raspi-config on the Raspberry Pi boards.

On Raspberry Pi, this tool is great and has both basic and advanced features like locale, expanding an SD cards file system, setting the system to read only, setting up wifi when not running a GUI and more... all things that you can get done in linux with experience... but it drastically helps the newer users.

I think this would benefit the Pine64 community with minimal work.

So i ran into this problem too. I used the steps in the guide you linked and it mostly fixed it. What i had to do to fully fix it was change my regional settings. Under system settings go to regional settings and update language and formats. If your language is really messed up and the system settings is in another language too its the 20th option in settings and the following 2 options in there. The icon kinda looks like a text bubble.
