like themselves dicen, the Service Packs of this operating system come with interesting news, but this time it has not been like that unless it is understood as "interesting" that it is safer. In last month's SP yes were included notable improvements, such as being uploaded to Phosh 0.21 and Phoc 0.21.1. The postmarket OS 22.06.3 recently launched it has a long list of new features, but in reality they could all be summed up in two, or one.
All items on the list except one say that have upgraded the kernel to a higher version, being the choice in most cases Linux 6.0.2. There are also cases in which Linux 5.19 or a newer version has been uploaded that already includes the patches, but all these points could be summarized in that the kernel has been updated to use one that already has the WLAN security problems patched. .
postmarketOS 22.06.3 does not include new features
Usually service packs are to bring features from edge to stable, and security fixes are pushed directly to stable without waiting for a service pack. However, this time the fix was not a trivial patch (like dirtypipe's), and we decided to update the kernel to version 6.0.2 when possible. This required more time for packaging and testing, and it made sense to bundle all of this into a service pack and make a proper announcement about it. So here we are.
The point that is missing, and in which the kernel has not been uploaded, has been for download the kernel version used by the Nokia N900. The old Nokia rocker (he's going to be 13 in the next few weeks) was running Linux 5.18.1, a normal cycle kernel that has long since reached the end of its life cycle. They might have ported it to Linux 5.19, if it wasn't for a recently discovered USB regression. Therefore, the only option left for them was to downgrade the kernel to Linux 5.15, the latest LTS version that is still supported.
To install postmarketOS 22.06.3, a new update was introduced some time ago. tool to update from the terminal. For those who do not have it installed, it can be added with the command apk add postmarketos-release-upgrade, and then launch it with the command postmarketos-release-upgrade. That is if you are in v21.12. For earlier versions, the installation commands would be:
wget https://gitlab.com/postmarketOS/postmarketos-release-upgrade/-/raw/master/upgrade.sh chmod +x upgrade.sh
