apparently my problem is I cannot update initramfs:
update-initramfs: Generating /boot/initrd.img-6.12.41+deb13-amd64 zstd: error 70 : Write error : cannot write block : No space left on device
After checking KDE Partition Manager for /boot and /boot/efi both have free space left:
/boot size: 488 MiB
/boot used: 396.26 MiB
/boot/efi size: 512 MiB
/boot/efi used: 10.52 MiB
dpkg -l | grep linux-image | awk '{print$2}' shows:
linux-image-6.1.0-37-amd64
linux-image-6.1.0-38-amd64
linux-image-6.12.41+deb13-amd64
linux-image-amd64
I am now using debian 13 on linux-image-6.1.0-38-amd64 because linux-image-6.12.41+deb13-amd64 won’t load from grub2. I don’t want to get rid of linux-image-6.1.0-37-amd64 till I solve this issue
Use Gparted boot disk. It’s a nice GUI program. It can resize partitions on the fly with data on them. It will move data within a partition if needed. I have successfully used it on XFS and BTRFS, YMMV. The usual advice of backup anything important is valid.
is gparted better than KDE partition manager? or gnome’s?
Haven’t used those but probably pretty similar.
Although it’s a bit dated, so I don’t think it supports luks in the GUI. You might have to use it as a visual reference and do it via the command line.
