The tarballs md5 is actually 2a5c84ae1e56bcc51d1aa54957d30bd6
I imagine that all these errors occur unexpectedly because GE releases hotfixes by replacing the tarball instead of uploading as a new file, so the URL is reused. This means that for every hotfix released, you have to update the PKGBUILD unfortunately.
