While your advice in itself is good, I’m afraid it doesn’t really help @anandm09 to solve this problem, @Mittineague. Please bear in mind that this place can be a bit intimidating to newcomers …
I am new to this Docker stuff myself, so unfortunately I am unable to provide him with the steps to proceed with the upgrade but I assume he’d need to free up some space on his installation first, before backing up his postgres database as suggested in the screenshot.
Would it be safe to do
./launcher cleanup
at this stage?
Perhaps you could point him in the right direction with that?
