I was uploading a snap to the store yesterday and got this message:-
“Error generating delta: delta_tool_path must be set in subclass!
Falling back to pushing full snap…”
What does it mean? Why does it appear? Should I care?
I made it go away (I needed it to go away because it’s a bit ugly appearing in a tutorial video I was making at the time) by deleting all of ~/.cache/snapcraft.
snapcraft as a snap? If so I think you need to install
xdelta3. If that works it means we have work to do.
Yes 2.32. Installing xdelta3 fixed it.
Just a reminder that this is still an issue. I just uploaded from a new machine and had the same problem
Error generating delta: delta_tool_path must be set in subclass!
Falling back to pushing full snap...
Still an issue… I just hit it with gimp.
Interesting you brought this up today, I created a PR for it yesterday https://github.com/snapcore/snapcraft/pull/2127
haha. awesome! Hooray for coincidence!
