From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Have you tried a normal "grub-update" command to make sure it gets the right kernel to boot up for you? Not 100% familiar with Ubuntu, but perhaps that's all you'd need to run to get it booting to the right version.
Yes, I've done that to no avail. And when I run "dpkg -l | grep linux-image" it shows I have five different kernels on my system, despite me only having the latest one installed through apt. Edit: Scratch that, I think I was misreading the input but the fact remains I can't seem to get rid of 6.2.0-24
Edit: autocorrect being annoying
Again, no Ubuntu expert here, so do this at your own risk (someone jump in and say this is a bad idea if it is). Not irreversible as you can just revert what I'm telling you via live CD, but just wanted to leave the warning.
If
uname -rshows the old kernel *-24, and grub update is choosing that instead of *-25, perhaps Ubuntu relies on the last change/created date or something weird. What you can check is if *-24 AND *-25 show up in /usr/src. If both are there, do (as root/sudo):mv /usr/src/*6.2.0-24* /root. Now rungrub-updateagain. I think it should tell you which version it chose for the boot menu.Next try:
grep 6.2.0 /boot/grub/grub.cfgto verify you see the new version.grub-updateagain.grub-updateto avoid not being able to boot back in. This wasn't the fix we were hoping for.^ this is all assuming Ubuntu puts its kernels in /usr/src and uses that location as reference to what's available/installed. If you see nothing there, then something else will need to be attempted
Edit 2: another thing to check is if the compiled kernels are in /boot. Basically follow the same instructions above but use /boot/*-24 instead. This might actually be what needs to be done now that I think about it, not necessarily /usr/src.
