When using eopkg (through the sorftware center or terminal), it gets stuck at downloading packages seemingly randomly.
This is apparently an issue with the software (nghttpd IIRC) on the RIT mirror, which we are not responsible for managing. Such package download timeouts occur to a fairly insignificant amount of our users but we're hopeful that it will be addressed either with our plan in January to move users to Fastly CDN, with the mirror as the backend (spoilers) or in changes on the mirror side. This is not specifically an issue with eopkg, just generic curl timeouts.
Marking as resolved since the issue is known and can really only be addressed with the two items I listed above. Such timeout issues are also a known issue by the mirror provider.
FYI it's lighttpd on mirrors. It actually is looking like a firewalld issue that has been affecting other areas as well. The owner of the server is in the process of bisecting the commit history in order to identify the regression point.
