Linux kernel question:
I manually upgraded a cloud virtual machine (test) running on Ubuntu 20.04 with a 5.4** kernel version to the latest 7.1 kernel available today:
https://kernel.ubuntu.com/mainline/daily/2026-05-13/I rebooted and it seemed to work fine. Apache web server is running. Doesn't seem to have any problems, but no load is on it.
Do you think it would be fine to run such an old 20.04 Ubuntu version with such a recent kernel? Or should I find a more recently released 5.** series kernel and try that instead?
I am testing getting kernels patched for the recent Linux vulnerabilities, but need to run older Ubuntu 20.04 for a while yet until web applications are manually ported to run on newer versions.
