Check your setup: Ubuntu 21.10, Wine 6.0, Gecko installed?
Find the newest Wine package for Ubuntu 21.10 and install it manually through Terminal. The latest version is 5.0.3, but it’s designed for Ubuntu 21.04. Since Gecko isn’t available, you’ll need to use the correct repository and follow the installation steps provided in the Wine documentation.
It’s generally preferable to use the versions included with the distribution. You might find it as a backport or via a user repository, though this isn’t always ideal for maintaining system stability. Gecko should be present in the official repository; you can look for it in the Software Center.
I wouldn't agree that sticking with the built-in version is ideal, especially for Debian/Ubuntu. The released versions often lag significantly behind the original developer updates. That's why WineHQ keeps its own repos to let users access the latest stable builds. Choosing an early Ubuntu release can be problematic because each new version introduces different library versions, requiring applications to be recompiled for compatibility. This means maintainers must adjust their build systems and release new packages, which can delay availability. Users should wait—updates may take weeks, but the updated repository will become available eventually. I'm also hoping Docker and Wine repositories will catch up before upgrading my server to 21.10. It will be a gradual process, but it will happen.
We plan to launch a WineHQ repository for version 21.10 after resolving issues with the build server.
