Trouble installing e/os on FP6 using the web installer on Linux

[piero]

i hope it can be usefull.

.

in 3 copy / paste actions !

.

because even well illustrated, the “web-installer” often don’t work,

and because the official documentation is imbuvable.

.

.

here we take the Fairphone 6 as example,
but it is the same logical and quite the same process for all the devices that have :

• only "IMG-e-xxxxxxxxxxx.zip" file on their download page,
• no "recovery-e-xxxxxxxxxx.img" file on their download page,
• no "recovery-IMG-e-xxxxxxxxxx.zip" file on their download page,
• that contains an install script named like flash_FP6_factory.sh.
