System information:

I am trying to do system image from docker image using brickstrap.

Then flashing ev3dev.img using Ether i getting empty folder. Same result using brickstrap installed from apt-get and github.

Also installed this packages

You need to use brickstrap create-tar to create the tar file, not docker save.

In this way?

fifi@tesla-vb:~/DockerSavedImages$ sudo brickstrap create-tar ev3dev/ev3dev-jessie-rpi2-generic ev3dev.tar
Checking docker image tar version...
tar 1.27.1-2+deb8u1

libguestfs: error: tar_in: write error on directory: /: 
fifi@tesla-vb:~/DockerSavedImages$ ls
ev3dev.img  ev3dev.tar

Ether still flash empty folder.

Sounds like this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1591617

This should be fixed in brickstrap already: https://github.com/ev3dev/brickstrap/commit/f7942f9f11481e19dbc6bb2c4b3d02a9dcb5a1a0

Yeah, it was this bug. Now everything works fine. Thanks!

Did you install brickstrap from the ev3dev tool PPA? e.g. what is the output of dpkg-query -s brickstrap | grep Version?

FRozanski commented 5 years ago

I installed brickstrap from this repo https://github.com/ev3dev/brickstrap

fifi@tesla-vb:~$ dpkg-query -s brickstrap | grep Version
Version: 0.6.3
dlech commented 5 years ago

Looks like we need to update the readme. The latest version is now hosted on launchpad:

sudo add-apt-repository ppa:ev3dev/tools
sudo apt update
sudo apt upgrade
