The link to download the VM in the Designing and Implementing Mobile Solutions course is broken in Firefox. It downloads a a small 1K ova file (mobility_718_VM_20160708.ova) file instead of the complete proper VM environment. This tiny file cannot be imported into Virtual Box.
Using IE - the VM is downloaded as a 6 Gb tar file. However it shows the following errors when attempting to uncompress the tar - Data Error in "Mobility Solutions-disk1.vmdk. File is Broken" and "Unexpected end of file". Of course, after you unzip the archive via 7-Zip and attempt to import into V-Box using the ovf - the import fails at the 55% mark of importing.
The import also fails into VBox if you attempt simply rename the tar extension to .ova --- then import the renamed file.
Also in Firefox the link to "Virtual Machine User Guide" does not launch when you click on it directly, you need to right click and launch the link in the new window to get it to work - this is not consistent with other courses and confusing to the user.
Can the course be configured so the proper & complete ova / vbox / ovf file is downloaded by the user using Firefox and IE? And the link to the user guide needs to launch correctly in Firefox. Also the "Virtual Machine User Guide" needs updating to properly reflect the file types that are actually downloaded, the expectations for unarchiving files which are in tar format, and a number of other items.
As a follow-up, the compressed VM package for the course is now updated so the file is not corrupted and can be imported into a VM environment successfully.
However please keep the following in mind:
The VM for the course will download as a tar file – you will have to change the extension to ova before importing it.
The PDF instructions for the networking for Virtual Box and other environments are incorrect. You will need to select the network setting as “Host Only Adaptor” and not Bridged Adaptor to get the course to work.
