Hi!

I am trying to use mender-convert.  
The first step after download is ./docker-build, but I get the following errors:

```

Hi @fisicator,

Unfortunately the 2.0.0 tag of mender-convert broke, because the Ubuntu base image that we relied on got removed (EOL).

Can you please try:

```auto
git checkout 2.0.x

```

And then run `./docker-build` again

Hi @mirzak,

Now I am able to run ./docker-build without error.  
I will proceed with the process.

Thanks!
