Help installing Playwright with Webkit on Fedora 41

[fantonangeli]

I needed to run Playwright tests using Webkit and update a snapshot test, but Fedora Linux is not officially supported by Playwright (https://playwright.dev/docs/intro#system-requirements). Only Ubuntu and Debian are officially supported.

Steps to Reproduce

Followed the official instructions for installing Playwright dependencies (https://github.com/apache/incubator-kie-tools?tab=readme-ov-file#step-1-bootstrap) with the following command:

PLAYWRIGHT_BASE__installDeps=true pnpm bootstrap

output:

packages/playwright-base install$ run-script-if --bool "$(build-env playwrightBase.installDeps)" --then "pnpm playwright install --with-deps"
│ [run-script-if] Boolean condition supplied.
│ [run-script-if] Conditions are checked using the operator 'and'.
│ [run-script-if] Condition is 'true'. Running _then_ command(s).
│ [run-script-if] Running 1 command(s): ['pnpm playwright install --with-deps']
│ [run-script-if] Running 'pnpm playwright install --with-deps'
│ BEWARE: your OS is not officially supported by Playwright; installing dependencies for ubuntu20.04-x64 as a fallback.

│ sh: line 1: apt-get: command not found
│ Failed to install browsers
│ Error: Installation process exited with code: 127
│ [run-script-if] Error executing 'pnpm playwright install --with-deps'.

How did I partially fix

4. Tried manual installation with:

    cd packages/playwright-base; pnpx playwright install

   This successfully installed Chromium and Firefox, but Webkit does not work.

How can I install Playwright with Webkit on Fedora Linux? Are there workarounds or additional steps I should take?
Thanks in advance

@fantonangeli Hey there! I'm not aware of any workarounds on how setup Playwright in Fedora, but I don't think this will work for the kie-tools monorepo as each OS has a slightly different screenshot, meaning the Fedora screenshot will be different of the Ubuntu that is used in the CI. I'm working in a solution to generate screenshots inside an Ubuntu container. I'll try to land a PR tomorrow or early next week.

Thank you so much, @ljmotta
