I am trying to run apt upgrade. However, I get:
...
E: mkinitramfs failure zstd -q -1 -T0 70
update-initramfs: failed for /boot/initrd.img-6.2.0-26-generic with 1.
dpkg: error processing package linux-firmware (--configure):

which I understand means my /boot partition is to small (seriously even on 18.04 which was originally installed on the machine there was no reason to have so small defaults).
ls -a /boot gives:
. config-6.2.0-26-generic initrd.img initrd.img.old memtest86+ia32.efi System.map-6.2.0-25-generic vmlinuz-6.2.0-25-generic

what files could I safely remove? What are my alternatives. This is my work machine, I would prefer not going down the reinstall path. There do not seem to be any old kernels.
This is the output of df
