[SOLVED] Cannot install Linux Firmware 1.187.14

[MarkusFueh]

Following a software update on LM20 a new kernel was installed (5.4.0 -74) and I couldn't boot because of "Kernel Panic". Synaptic showed a broken package but trying to repair / remove to broken package didn't work, however it caused that I was able to boot with the new Kernel. I was then upgrading to LM20.1 in the hope to fix bugs but the update manager displays the above mentioned firmware which I can't install

At the end of the installation process, a window pops up that says:
E: /var/cache/apt/archives/linux-firmware_1.187.14_all.deb: cannot copy extracted data for './lib/firmware/iwlwifi-8265-36.ucode' to '/lib/firmware/iwlwifi-8265-36.ucode.dpkg-new': unexpected end of file or stream

And the terminal window of the installation says:
/var/cache/apt/archives/linux-firmware_1.187.14_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:

When I run "sudo dpkg ––configure –a":
dpkg: error: need an action option
Type dpkg --help for help about installing and uninstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list f forcing options;
Type dpkg-deb --help for help about manipulating *.deb files

I tried many other sudo commands but all fails.

My system is a HP notebook, Intel© Core™ i7-6500U CPU @ 2.50GHz × 2

Sounds like a download issue. Something went wrong during the download of the package. Do:

Code: Select all

sudo apt clean
sudo apt update
sudo apt upgrade

That worked really well and easy - Many thanks for your prompt assistance

Excellent!

Just to explain: Normally apt downloads the files it needs to install, and keeps them in a cache inside /var/cache/apt. When you try to install a package it will look into the cache and avoid re-downloading it.

sudo apt clean will force to delete all that cache, which will force a re-download of the files.
