spaceship update to 1.4

blyth

I am unable to upload the latest theme update (have been overseas for two months) without getting the following message:

"An error occurred while updating Spaceship: Update package not available.."

I have tried to upload automatically through WP and am not able to see how I would do it any other way. Before I know I updated manually to get 1.3.

Thanks in advance for your help.

This for our other theme, but same steps.

With regards.
