After application of R2022b_upd5 on linux mint (21.1 Cinammon) I always get the following warning at the startup: Warning: X does not support locale en_US.UTF-8 But the MATLAB has proper "locale" feature:
>> feature('locale')
ans =
struct with fields:
ctype: 'en_US.UTF-8'
collate: 'en_US.UTF-8'
time: 'en_US.UTF-8'
numeric: 'en_US_POSIX.UTF-8'
monetary: 'en_US.UTF-8'
messages: 'en_US.UTF-8'
encoding: 'UTF-8'
terminalEncoding: 'UTF-8'
jvmEncoding: 'UTF-8'
status: 'MathWorks locale management system initialized.'
warning: ''
Any idea what is wrong after update5?

@Cheliza Everything (!!!) mentioned in your comment does not work at all.

Why is this still broken? Just installed 2023a Update 2 on Ubuntu 22.04 and I'm getting the warning. Why? It looks like you promised to fix this long ago.

Official TMW statement:
"This is a warning message that can be disregarded and it has no impact on the functionality of MATLAB. A future update for R2022b and R2023a will remove this warning. Using previous updates of R2022b will not display this warning."

This seems to be an issue for R2022b Update 5 and R2023a on any Linux distro. My installs on Ubuntu, Debian, CentOS, and Arch have all done the same thing after going to Update 5. I have not found a workaround yet and will update this post when I do.
EDIT: The only reasonable workaround I've found is launching MATLAB with matlab -r clc

Isn't X the window management system? That would suggest this is not necessarily related to Matlab itself.
This thread is for Ubuntu, but you can give the commands a try anyway.
Or you could try 1 Google result below, which is a decade old, but is specific to Mint.

Brand new fresh install of both Ubuntu and Matlab R2022b Update 5 as of March 10 2023 and I get the exact same warning/error first time and every subsequent time I start Matlab. I even tried regenerating the locale profiles based on this: https://askubuntu.com/questions/99651/apt-get-warning-no-support-for-locale-en-us-utf8
with no change.

Warning: X does not support locale en_AU.UTF-8

"This is a warning message that can be disregarded and it has no impact on the functionality of MATLAB. A future update for R2022b and R2023a will remove this warning. Using previous updates of R2022b will not display this warning."
The fact that the warning did not appear in previous versions of Matlab, and does now, and that a fix has been promised, but has not been provided, does not bolster confidence in Matlab. It's like a little tag line that says "Hey! We're Matlab! We don't take details seriously!".
And I know that MW DOES take their product seriously. Suggest that this be addressed. A reminder of a bug every time one opens Matlab is not a good look!
