tar: This does not look like a tar archive tar: Exiting with failure status due to previous errors. Singularity 2-4 on vagrant on windows10

[Aaron Dickey]

Hi,

Things had been going swimmingly until a few weeks ago. This set of image.create and build commands used to go off without a hitch. Now I am not able to use my favorite docker image as a singularity image base anymore:

cd .\singularity-2.4\

vagrant init singularityware/singularity-2.4

vagrant up

vagrant ssh

sudo singularity image.create --size 3000 drvm.img

sudo singularity build --writable drvm.img docker://990210oliver/drvm --debug

Please help!

I was getting the same error. I think this is related to the same issue reported here:

https://github.com/sylabs/singularity/issues/1939

I resolved the issue by simply deleting the '.vagrant' directory in the folder I was working out of, which causes a new Vagrant virtual machine to be created. After this, the container built fine. Just keep in mind that the old VM is still going to be running in VirtualBox, you will want to remove it there as well.
