Bad mirror for Discord 0.0.27

[falkreon]

Steps to reproduce:

• Follow the PPA install steps for the "all" channel on https://blog.javinator9889.com/discord-ppa-keep-it-up-to-date-on-linux-easily/
• perform sudo aptitude update or equivalent apt or apt-get commands

Expected behavior: Fetch from the official PPA yields metadata for latest stable Discord release.

Observed behavior: Failure to validate artifact metadata with the following relevant messages:

E: Some index files failed to download. They have been ignored, or old ones used instead.

Time has been allowed in case the PPA is mid-mirroring, but the problem still persists. Past discord updates have pulled just fine for me.
