Failed to open the disk image file /tmp/tde-ubuntu-14.04-desktop-latest-amd64.iso.

Could not get the storage format of the medium '/tmp/tde-ubuntu-14.04-desktop-latest-amd64.iso' (VERR_NOT_SUPPORTED).

Result Code: VBOX_E_IPRT_ERROR (0x80BB0005)

The problem is that the file size is not a multiple of 2048.

Padding it with

printf '%1536s' ' ' >> tde-ubuntu-14.04-desktop-latest-amd64.iso

makes VBox happier about that image.

///

 2048 - (.iso size mod 2048) = printf size

BREAKING: After @GregAbbott_TX surged @TxDPS troopers into Del Rio, it appears that illegal migrants crossings at the river have come to a halt for now. DPS tells me hundreds of their troopers are now there to provide security and a physical deterrent.

The Texas Department of Public Safety is in full force along the border around the Del Rio area.

They have built a barricade with their squad cars and State Troopers.

The National Guard is working with them to secure the border.

I’m now on the U.S. side of the Rio Grande where thousands of migrants crossed illegally into Del Rio today. The migrants left piles of trash, and the area has now been secured with barbed wire by Texas DPS. The flow of migrants has stopped & DPS is here in force. @FoxNews //

DPS Troopers and @TexasGuard remain on the scene in Del Rio to monitor the #bordercrisis. Thanks to @GovAbbott’s leadership and support from the #txlege, #OperationLoneStar allows Texas to step up where the federal government has failed to #securetheborder.
