Travis-CI is sunsetting the free travis-ci.org service at the end of this year and encouraging users to migrate to the commercial travis-ci.com service with severely limited minutes. Now that Gridsync has enabled GitHub Actions -- and because Travis-CI has been notoriously unreliable and slow over the last couple of years to the point of impeding development -- there is little reason to proceed with the migration to Travis-CI. Instead, Travis-CI builds should be disabled for the Gridsync project and any related configuration files, etc. should be removed.
