I need to install Linux, better Ubuntu, to my 4 GB flash-drive. As 4 GB is too small for normal desktop version of Ubuntu I have downloaded alternate version through here because of recomendation from here. But there are few problems with installation. Almost at the start of the process it shows up first error:

Some of your hardware needs non-free firmware files to operate.  The firmware can be loaded from
removable media, such as a USB stick or floppy.

The missing firmware files are: iwlwifi-7260-9.ucode iwlwifi-7260-8.ucode

If you have such media available now, insert it, and continue.
Load missing firmware from removable media?

After which was second error: 

The missing firmware files are: rtl_nic/rtl8411-3.fw

I have found some useful information about this on the internet, but thats all I found. In that topic author uses debian and debian commands, so I can't use it personally. But I have downloaded firmware-iwlwifi_0.43_all.deb and can not unpack it.

Any ideas how to fix this?

Laptop: Dell Vosto 5470.

First run dmesg in the terminal to get diagnostic data as follows.

┌──(rootkali)-[~]
└─# dmesg
Then you will get missing firmware failed to load  highlighted in red as
[   13.491010] iwlwifi 0000:01:00.0: firmware: failed to load iwl-debug-yoyo.bin (-2)
[   13.491013] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware

Copy the firmware info after failed to load (iwl-debug-yoyo.bin) in this case.

Then enter this command followed by the missing firmware you copied from above like this:

┌──(rootkali)-[~]
└─# apt-cache search iwl-debug-yoyo.bin
firmware-nonfree-contrib..............90393jklflsdk

Then you get this. Finally, install that firmware by running this command/

┌──(rootkali)-[~]
└─# apt install firmware-misc-nonfree........-090-9-0sdlf

Don't forget to replace firmware-misc-nonfree with what you obtained by following the procedure.

The iwlwifi firmware pertains to your wireless card. Go here:

http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005511.html

And download the correct 7260 driver. Unzip the .ucode files and put them on a usb. You can also skip the error and later put the .ucode files into /lib/firmware.

The second error pertains to your Ethernet port. You can also skip that error, download the drivers here:

https://packages.debian.org/jessie/firmware-realtek

and place the correct .fw files within the /lib/firmware folder.

Also, which version are you installing? 16.04 should have full support for the 2 previous devices.

--upvote if this helped :)--

The package linux-firmware contains the file: /lib/firmware/iwlwifi-7260-9.ucode

If you have ethernet setup, then do:

sudo apt-get install linux-firmware

If not download the deb file. Make sure that you choose the correct distribution version.

Then,

sudo dpkg -i *.deb

BTW Debian commands do work in Ubuntu.
