Kernel update fails with odd error message

When I did the upgrade to 20.1 I started getting error messages regarding a kernel upgrade. The update manager would notify of an available kernel upgrade. I'd apply the upgrade and get this error message:
Code: Select all
E: /var/cache/apt/archives/linux-modules-5.4.0-60-generic_5.4.0-60.67_amd64.deb: cannot copy extracted data for './boot/System.map-5.4.0-60-generic' to '/boot/System.map-5.4.0-60-generic.dpkg-new': failed to write (No space left on device)
E: /var/cache/apt/archives/linux-image-5.4.0-60-generic_5.4.0-60.67_amd64.deb: cannot copy extracted data for './boot/vmlinuz-5.4.0-60-generic' to '/boot/vmlinuz-5.4.0-60-generic.dpkg-new': failed to write (No space left on device)
I then got a lot of broken package error messages. I tried fixing them with synaptic package manager, then manually with various combinations for apt and dpkg as suggested by web searches. There have been no catastrophic failures but I'm stuck at my current kernel version.
hostnamectl returns:
Code: Select all
Operating System: Linux Mint 20.1
Kernel: Linux 5.4.0-58-generic
Architecture: x86-64
This is accurate, I'm running on a Dell Latitude with an Intel processor. Note that the error message refers to /var/cache/apt/archives/linux-modules-5.4.0-60-generic_5.4.0-60.67_
amd64.deb I suspect this is somehow the source of the error but my CLI-fu is too weak to use that clue.
Any and all help and advice greatly appreciated.

(No space left on device)
Check your disk space.

I lot of things will fail until you fix that problem.
Please post the output of
and, to see where the disk space is being used, also run
which will list the directories under "/" and their sizes, with the largest at the end.

Here's the df dump -- sorry the formatting is so bad, it looked OK when I entered it and I don't know how to toggle of whitespace stripping:
Code: Select all
Filesystem 1K-blocks Used Available Use% Mounted on
udev 3968264 0 3968264 0% /dev
tmpfs 802844 1644 801200 1% /run
/dev/mapper/mint--vg-root 120817368 46214748 68422372 41% /
tmpfs 4014204 800 4013404 1% /dev/shm
tmpfs 5120 4 5116 1% /run/lock
tmpfs 4014204 0 4014204 0% /sys/fs/cgroup
/dev/sda1 720368 701184 0 100% /boot <===== full 100%
tmpfs 802840 20 802820 1% /run/user/1000
The culprit seems to be /boot but I'm not sure since I went for whole disk encryption when I installed Linux.
GParted shows /dev/sda1 as the boot partition with size = 731 MB, Used = 712.27MB which is basically 0% available. GParted also says none of the partitions can be resized, presumably because they're inside the encrypted partition.
If any of this information provides a useful clue, again, thank you in advance.
Meantime I'll to some research on resizing encrypted partitions.

For future reference, you can use
code tags around the output you posted, to keep its formatting in-tact. Here's an image which might help:

You most likely need to remove an old kernel or 2. From the menu, click System --> Update Manager. Click View --> Linux Kernels. Then click Remove Kernels. I recommend keeping at least 2; one will be the current one which you can't remove.
