I need edit USB stick disk by adding a file with firmware to my wifi card and lan card when I try install I see error.

How to change permission to add files into USB boot disk working on UBUNTU 17.10??

ISO downloaded from this source: iso-dvd/

Disk created by UBUNTU Startup Disk Creator

df -h:

/dev/sdc1       3.8G  3.8G     0 100% /media/xxx/Debian 8.11.0 amd64 1

sudo lsblk -f

Compare this line

sdc  iso966 Debian 8.11.0 amd64 1
                                 2018-06-23-13-24-25-00

with the correspoding line, when I loop mount my similar iso file

sudo mount -o loop debian-live-8.8.0-amd64-standard.iso /mnt/lp1

$ sudo lsblk -f
NAME   FSTYPE   LABEL                         UUID                    MOUNTPOINT
loop0  iso9660  Debian jessie 20170506-14:26  2017-05-06-13-27-04-00  mnt/lp1

You see that there is an iso 9660 partition structure and file system, which is typical for a system, cloned from a hybrid iso file. The iso 9660 system is read-only by nature, and cannot be modified.

So you need to use an extracting tool (not a cloning tool), if you want to be able to modify it. But I am not sure that a live or persistent live system will be able to take advantage of the firmware you want.

Instead I suggest that you create an installed system in your USB drive (installed like into an internal drive), and install the firmware (and maybe drivers and other software) into that system. See this link (and modify it to take into consideration, that it is not an Ubuntu system, or simply try the newest Ubuntu system, 18.04.1 LTS).
