Can we split out the parenthesized bit for clarity? Something like Invalid TUF data will cause the update to fail, for example if there was an invalid root rotation

Should we call offlineRepo.Update(false) and verify that it errors?

If the client is in offline mode, or encounters some kind of network error when downloading a new timestamp, it should fall back on using the version of the repo in the cache.
Since there a huge number of possible network errors, just wrap any errors received when actually making the HTTP request using the remote store in a
NetworkError.
