Hi, Mender team I’m currently have a Mini PC at home, and I want to deploy use Mender to deploy some service (such as web server) on it, but I have some difficulties on converting Debian container image. It would be great if I can have your’s support. **1. Mini PC** I have a fresh Centos 7 netinstall with docker installed, I have connected this OS with my mender account. ![image](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/c6bb33ac7515bb64b041e519a66d9a1ebfb006bb.png) **2. Virtualbox** I am using Virtualbox to install a Debian 9 with nginx for testing web service. This OS contain 2 disk: - 1 for OS - 1 for create _file_.img and converting ![](https://lh4.googleusercontent.com/VrmJ_6mV7aTWUCIATeutlupjUCajwQR7ekIXmEL35byLhbXCVhW_k6NVO-kbVl9Jrm3wdWUga8Xj8DLxfhp4jpxthf1OC18wYeSFe2bjUksRXu2wosb9eeem-PyynuaKfdmL1v5x) I have create a golden image with this command _$ dd if=/dev/sda of=/home/tel4vn/golden-image-1.img bs=1M conv=fdatasync_ But when I run command to convert image there is some error and it stop converting ![](https://lh3.googleusercontent.com/7PHmridIqPsAvpGziah6tf6fApxMmCsf7jvR_H33ZSenQpCzCRBF6ujF7BmT2nx7Jx7MXvyufil8ApNs5VwKuqUsy7fUSACpGEimGp08m-bB0ifXtHOaHnbzhbtwlyocJgHQkXAX) When I install mender-convert I’m using branch 2.2.x because there is no branch 2.2.0 arcording to this document. > **[Convert a Mender Debian image | Mender documentation](https://docs.mender.io/system-updates-debian-family/convert-a-mender-debian-image)** Please help me with this, I’ll be much appreciated. ---

@M.Tuan welcome to the mender hub. How was original image generated? What os type do you use for rootfs. Currently olyn btrfs + ext4 are supported (AFAIK Centos by default use lvm). Thanks. ---

I build a Debian 9 netinstall on Virtualbox and then create a golden image from there, with this command _$ dd if=/dev/sda of=/home/tel4vn/golden-image-1.img bs=1M conv=fdatasync_ Does it answer your question? About the CentOS on Mini PC problem, I’ll reinstall it into Debian 9, and use it to connect to Mender3, is it right? ---

I seem to recall having to explicitly disable the swap partition when I was working with CentOS earlier. You may want to give that a try and ensure there is just the one partition on the disk. Drew ---

But I’m converting image on Debian 9 on Virtualbox on my laptop. On my Mini PC I’m just installing docker on it, and connect it to Mender I also try to disable swap space on Debian 9 ![image](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/719c54e114ef560f4b95e5e11c87749dc927b667.png) ![image](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/651a2450495fd75c3bcdbc19f16de707956517ca.png) But then this error appear when converting ![image](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/6ff24ae0de4fd6d5bc9ae888dd9533196c83838f.png) ---

Seems you cannot fetch package from internet. Does host machine have internet connection? Seems wget failed. ---

If you try to use same artifact it won’t work because version will be same so you need to build other artifact with other release number and then try again. ---
