This is definitely a PC so this must be the installer thinking it might be a laptop.
I looked because "apt upgrade" failed to install things in /boot because noroom left. I deleted the oldest kernel stuff of the 3 there and "apt upgrade" worked. I was thinking then to remove the unwanted modules to make the kernels smaller.Modules are sitting on disk waiting to be loaded into memory if they're needed. lsmod shows the ones that are currently loaded into memory. Removing one from memory with rmmod(8) or an equivalent will not reduce the amount of disk space they take up. All it will do is free a tinybit of RAM, and sacrifice the functionality being provided by the module.If disk space is a serious issue for you, rmmod(8) will not help.
this is after <cough> deleting the very oldest. root@pumpkin:/boot# ls -la total 148944 drwxr-xr-x 4 root root 1024 Jul 3 16:53 . drwxr-xr-x 20 root root 4096 Jul 3 16:45 .. -rw-r--r-- 1 root root 236065 Apr 9 19:17 config-5.10.0-6-amd64 -rw-r--r-- 1 root root 236188 May 28 09:31 config-5.10.0-7-amd64 drwxr-xr-x 5 root root 1024 Jul 3 16:45 grub -rw-r--r-- 1 root root 68868137 Jul 1 16:17 initrd.img-5.10.0-6-amd64 -rw-r--r-- 1 root root 68909875 Jul 3 16:53 initrd.img-5.10.0-7-amd64 drwx------ 2 root root 12288 Nov 21 2020 lost+found -rw-r--r-- 1 root root 83 Apr 9 19:17 System.map-5.10.0-6-amd64 -rw-r--r-- 1 root root 83 May 28 09:31 System.map-5.10.0-7-amd64 -rw-r--r-- 1 root root 6824192 Apr 9 19:17 vmlinuz-5.10.0-6-amd64 -rw-r--r-- 1 root root 6818304 May 28 09:31 vmlinuz-5.10.0-7-amd64 root@pumpkin:/boot# du -h /boot 12K /boot/lost+found 2.1M /boot/grub/i386-pc 2.3M /boot/grub/fonts 4.3M /boot/grub/locale 11M /boot/grub 157M /boot root@pumpkin:/boot# df -h /boot Filesystem Size Used Avail Use% Mounted on /dev/sdb1 236M 159M 65M 71% /bootCan I not *just* move the older ones out of the way so upgrade doesn't run out of space ?
