When I’ve tried to compile and upload the latest version of Musescore (3.0.2) I got a manual review warning from the store. This is the rejection message I got:
Rejected by Jamie Strandboge. “Found files with executable stack. This adds PROT_EXEC to mmap(2) during mediation which may cause security denials. Either adjust your program to not require an executable stack, strip it with ‘execstack --clear-execstack …’ or remove the affected file from your snap. Affected files: usr/lib/i386-linux-gnu/libQt5WebEngineCore.so.5” — Jamie Strandboge
But I don’t really get it: that file was already there is the last version of the snap (3.0.1), so why it’s now a problem @jdstrand ?
