[SOLVED] No file name for linux-firmware amd64

[IanSammel]

Up to now I have had no problems. Then a few days ago I tried to install the latest updates including the kernel version 59 and the update failed because of a problem apparently with linux-firmware. I tried to reinstall linux-firmware from the command line and got the error:
E: Internal Error, No file name for linux-firmware:amd64
The processor is an Intel core i5.
The kernel 59 wasn't installed and the system still booted from 58. I decided to wait a few days to see what happened. Kernel 60 appeared but the update still failed with the same error. This is the error message from muon:

"linux-firmware
installed linux-firmware package post-installation script subprocess returned error exit status 1

linux-image-generic
dependency problems - leaving unconfigured

linux-generic
dependency problems - leaving unconfigured

linux-image-5.4.0-60-generic
installed linux-image-5.4.0-60-generic package post-installation script subprocess returned error exit status 1

linux-image-5.4.0-59-generic
installed linux-image-5.4.0-59-generic package post-installation script subprocess returned error exit status 1"

dpkg --audit just tells me that linux-generic, linux-image-generic, linux-firmware and linux-image-5.4.0-60-generic are not configured (I uninstalled the 59 kernel) Command line install still tells me E: Internal Error, No file name for linux-firmware:amd64
I get the same error if I try to reinstall linux-generic and linux-image-generic
I have tried dpkg --configure --pending but that doesn't help. In the meantime the 60 kernel has become the grub default and the boot just hangs so I have to boot 58 from the advanced options which still works. (I suppose I could reconfigure grub or uninstall 60 but I want to make as few changes as possible in case I mess something up completely)
Does anyone have any idea what's going on and how I can solve the problem? Thanks!

Maybe a space (as in, available spacer) issue on your root ( / ) partition? In a konsole, what does the command df -h show? Copy/paste the output in your reply inside of code tags.

[IanSammel]

I don't think it's a space problem. Here's the output of df -h

Can you at least boot into the previous kernel?

[IanSammel]

Can you at least boot into the previous kernel?

Yes, booting into 58 is no problem. I just can't upgrade any further. Muon always exits with
"post-installation script subprocess returned error exit status 1"
If I try to complete the configuration of unconfigured packages or reinstall linux-firmware from a terminal I get the error
"E: Internal Error, No file name for linux-firmware:amd64"

The linux-firmware package is installed. The problem is with the configuration.

SOLVED No file name for linux-firmware amd64

Problem solved and it was a really stupid thing. After staring at the error messages for days I finally realised that as part of the configuration process, a routine named iscan is called. A week or so ago I dug out my old Epson scanner and installed the software to drive it - a program called iscan. Deleted the Epson software and everything works fine.
