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.


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


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:


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.

  • I'll try right now. There is no alternate version 16.04, only 12.04.5. With 16 everything worked, except there was not enaugh space on flash-frive. – Telion Sep 25 '16 at 14:03
  • You don't need the alternate for a full install on a USB. You should be able to install on a USB just like any other storage medium. I did it on my 16GB Sandisk Ultra Fit. Just disable journaling and swap. – negusp Sep 25 '16 at 14:08
  • I have 4GB flash drive. When I was trying to install ubuntu-desktop 16.04 on it I got error "not enaugh space". Is there really any chance to make it work though? – Telion Sep 25 '16 at 14:14

    Unpack it on a separate computer, or skip the error and install later. The Ethernet and Wifi errors aren't crucial to the installation. I would install something other than Ubuntu on a 4GB flash drive. Slax comes to mind. 4GB will be very tight, especially under Ubuntu. – negusp Sep 25 '16 at 14:21

    Slax, Puppy Linux, etc. If you really want Ubuntu/Debian, install it as a Live CD on a USB, and then enable persistence. Guide here: help.ubuntu.com/community/LiveCD/Persistence – negusp Sep 25 '16 at 14:31

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.


sudo dpkg -i *.deb

BTW Debian commands do work in Ubuntu.
