Non x86-64 architectures are not well supported #253

Closed Happy-Ferret closed 7 years ago

Running the following command fails to build the image, leaving that subuser id in a broken state. 

subuser subuser add vim1 vim@default

I used the alias "vim1" because the build already failed once and I still have to figure out what files I need to remove in order to properly get rid of the image again.

System: 

Ubuntu 15.04 (3.19 kernel@stock) i686
Python 2.7.9
Docker 1.5

Subuser was installed through pip.

The problem is that subuser is using the default images from the Docker hub, and these images do not support 32 bit systems (you write that you are on i686). https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1366509

It may be possible to create subuser repositories for non x86-64 architectures, I haven't tried it yet. But it is not a priority for me.

I'm sorry that the error message is not more user friendly. It should tell you the problem clearly and imediately. However, that would be a bug to file against ubuntu's version of Docker and not a bug in subuser.

Have a nice day,

Timothy Hobbs

Thanks. That's good to know.

Not a problem at all either. I normally run x86_64 OS' anyways. Was just a quick spin-up and that 32 bit Ubuntu ISO happened to sit around on my HDD.

I'll report back once I've set up a proper 64 bit distro.

I'll definitely look into creating ARM64 based repositories too, since those are a target platform for one of my projects.
