Log Output

None to report as it is a packaging issue

Additional Information

This is to the rpm packages still using md5 digests. Which is not supported on el8+ with fips policies in place. (sha256 digests are required)

fpm [ "--rpm-digest=sha256"] looks to be needed to be added to the build process for rpms, but I am not familiar enough with electron to know how to do so properly.
