We haven’t made any changes to our snapcraft.yaml file for more than 9 months, and from last 4-5 days the snap build failed once. So we ran snapcraft clean and then build the package successfully.
But when we launch the app, it crashes with the following error message:
libEGL fatal: did not find extension DRI_Mesa version 1
It is flutter app that uses python based opencv. Any help would be appreciated. Here is the snapcraft.yaml file:
