Problem updating Debian version on Dell M300 (3 replies)

Tried to update the Debian 10 (Buster) file system on my Dell M300. Did apt-get update followed by apt-get upgrade and ran into this:

Processing triggers for initramfs-tools (0.133+deb10u1) ...
update-initramfs: Generating /boot/initrd.img-5.5.1-kirkwood-tld-1
W: missing /lib/modules/5.5.1-kirkwood-tld-1
W: Ensure all necessary drivers are built into the linux image!
depmod: ERROR: could not open directory /lib/modules/5.5.1-kirkwood-tld-1: No such file or directory

depmod: WARNING: could not open modules.builtin at /var/tmp/mkinitramfs_vDDIAc/lib/modules/5.5.1-kirkwood-tld-1: No such file or directory

It looks like it created this image file:

-rw-r--r-- 1 root root 5007694 Feb 13 15:03 initrd.img-5.5.1-kirkwood-tld-1

It is about half the size of the 5.2.9 image files.

I did update-upgrade on a Pogo E02 last weekend and it worked fine including regenerating the uInitrd as directed after the updgrade completed.
