I am trying to get through prerequisites.sh but it keeps throwing this error at me.  
E: The repository '[Index of /openjdk-r/ppa/ubuntu](https://ppa.launchpadcontent.net/openjdk-r/ppa/ubuntu) kinetic Release' does not have a Release file.  
N: Updating from such a repository can't be done securely, and is therefore disabled by default.  
N: See apt-secure(8) manpage for repository creation and user configuration details.  
How do I fix this?

Try replacing kinetic with jammy

/etc/apt/sources.list.d/[jre something] ?

idk what ur Environment for building image sir.

but here is a guideline i posted.

[https://ssafy.tistory.com/4](https://ssafy.tistory.com/4)

once u hav succeed building,  
then you can build much faster by using S-STATE.  
and you can edit built-in test Apps by editting

~/build-webos/meta-webosose/meta-webos/recipes-core/packagegroups/packagegroup-webos-extended.bb

then build again after rm build folder.

```auto
$ cd build-webos
$ sudo rm -rf BUILD
$ source oe-init-build-env
$ bitbake webos-image or webos-image-devel

```

IIRC you don't really need openjdk to build webOS OSE, just remove this part from prerequisites.sh and run the build.

localization-tool-native doesn't use openjdk since [native: localization-tool-native=r2 com.webos.app.home=10-r2 imemanag… · webosose/meta-webosose@1c077e1 · GitHub](https://github.com/webosose/meta-webosose/commit/1c077e1147e5e1c5865439e518bad55f4e75efcf)
