I'm updating to the newest version of IBM DSX Desktop 1.1.7. The install process stalls and displays 

"Downloading DSX... 0%".

The file desktop.log ends with lines 

“The size is 83.85 and installsize is 14.73”

and 

“Docker Storage Requirement Failed”.

The Docker app is up to date. I’ve tried the usual reboot, etc without success. Any clue?

In my case, dsx-desktop.log has the following error:

[2017-11-04 19:52:03:0214] [error] exec error: Error: Command failed: eval $(docker-machine env ibm-dsx) && docker system df
docker: 'system' is not a docker command.
See 'docker --help'.

[2017-11-04 19:52:03:0214] [error] stderr: docker: 'system' is not a docker command.
See 'docker --help'.

It turns out "docker system" command is only available after Docker API version 1.25. Check your API version from the output of "docker version".

After I reinstalled a docker version with API version 1.33, it is able to download.

  • I've checked I'm using the last version. `[2017-11-06 11:13:31:0696] [info] Docker Version: Docker version 17.09.0-ce, build afdb6d4` I've executed as Admin too. – SebasT Nov 06 '17 at 14:43

I work on the DSX Desktop team. You might be encountering a bug with the installation code. The good news is that it's a pretty simple fix if you are. Here's how to check:

Diagnosis & Fix

  • Open up your terminal or command prompt and run docker system df. Look for the entry that corresponds to IMAGE SIZE. If the unit is in kB or B, then you're encountering the bug.
  • To fix it, run docker pull busybox. Once the pull completes, you should be able to update DSX Desktop. After it successfully updates, you can run docker rmi busybox.
  • If the unit is in GB, then that means your existing images are taking up too much space. The limit is 60GB so make sure your IMAGE SIZE + installSize <= 60GB.

Explanation

  • There's a typo in the code that causes the installer to mistake kB and B for GB. Thus, if you have an IMAGE SIZE of 83.85kB, the installer will treat it as 83.85GB and will complain about being over the 60GB limit.
  • So to fix it, we pull a temporary image busybox, which updates our IMAGE SIZE to be in MB, allowing us to avoid the bug. After we successfully update DSX Desktop, we can remove the temporary image.

This has been patched and will be fixed in an upcoming release.
