Hi!
I am having problems getting the Jenkins UI to show up in anything but English. My browser correctly outputs an Accept-Language string:
Accept-Language: sv,nb;q=0.9,en-US;q=0.8,en;q=0.7
but the user interface still displays in English.
If I request the same document with my phone browser, the UI shows in Swedish, so I know it is capable. The mobile version sends
Accept-Language: sv-SE,sv;q=0.9,nb-NO;q=0.8,nb;q=0.7,en-GB;q=0.6,en;q=0.5,en-US;q=0.4
I am running Jenkins 2.462.3 installed from .deb package, running on an Ubuntu 24.04 LTS server. The Jenkins Java app is responding directly on port 80, there is no intermediates to rewrite the queries.
Using Vivaldi (7.0.3495.6) on Debian desktop (displays English) and Vivaldi for Android (6.9.3451.114).
