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.

Your entire disk is already allocated. You can't easily shrink anything and move space around.
You also shouldn't need to expand your boot partition at all.
Who or what is telling you this is needed?
debian 13 needs more boot space, my boot partition is too small to complete the upgrade
Have you tried to do some cleaning on your
/bootfilesystem? It could be you have some old stuff there that may well be wasting storageYou can resize partitions if disk is all full...depending on fs of course...but shrink, move, grow works.
still don't follow: should I shrink instead of resize?
I typically use gparted live, or GNOME disk utily, so I don't know the command names, I slide the sliders and hit OK 😀
