I'm pleased to report that the HG repository service (hg.ginever.net) is now tentatively reopen. The newly updated service is powered by the latest version of Kallithea SCM.
As part of the update, Kallithea has been patched to support 2FA codes during the login process, along with push and pull by using SSH/pageant. These two changes were required in order to support GineverAccount 5.1 and are effectively tied together, because the 2FA codes break the username/password authentication typically provided over https, meaning that people with 2FA enabled are effectively forced to use SSH instead.
Because these patches are experimental, they are not very well tested, and may end up causing minor problems. As a result of this, the new service will be shadowing the Bitbucket repositories until I'm happy that it is decently stable, and may be subject to arbitrary patches and bug fixes. Any issues you discover should be reported to me directly.
Please note that if you wish to use the service, you will have to head over there and (if needed) input your SSH public keys into the control panel in the exact same way you previously did at Bitbucket. Please contact me if you think you need help with this.
