You will probably need to include a bit more information about the build (logs, snapcraft.yaml too) if you expect anyone to be able to help you with this.
Hello,
Just in! I was getting one too, likely introduced with a recent routine update ( > 10 hours ago) upgrading to snapcraft, version 6.0
.
Sometimes I experience occasional problems that just need a retry, but this one stuck. Started to try attentively up/downgrading, a
snapcraft refresh
seems to have sorted it. Not sure it’s the same thing, for the record, the call stack here was as below.
Best,
Janos

(Sent it in as well a few times.)
after using a snapcraft command to build a simple hello world printing snap. I have received this much error on the console.
My snapcraft.yaml

snapcraftctl build
cd /home/pramod/Practice/hellosnap/
./buildhello.sh
My buildhello.sh
echo “Building Print Hello Msg” echo “” pwd echo “”
cc hello.c printmsg.c -o Hello
cp Hello Output/.
ls -ltr Output
echo “Compilation Done” echo “”
My snap was working fine till now, suddenly it started showing the error.
It looks like the new software expects the (old?) data to have a key that’s not there. Kick the upstream devs to have that handled gracefully. That being said I would 247% have made such an error.
