Details of the issue:

I can't load any pack.
In the first try it gets file not found for ForgeMultipart-1.7.10-1.1.2.332-universal.jar
There after it just doesn't load.
Attempted packs: Infinity, Direwolf20, Monster(1.6.4)
attempted java versions: oracle 1.7.0_80, oracle 1.8.0_31, openjdk (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2)

forced update, clean FTB launcher install.

Using ubuntu 14.04, it worked 3 or 4 days ago, I have no clue what changed.​

Have you tried reinstalling the whole ftb launcher, because that might help

I tried reinstalling a few times, same dir, different dir, new user. No luck.

UPDATE: Full OS reinstall, still not working.

FINAL UPDATE and solution:
I installed MultiMC, and it works through that.
So the issue appears to be with the FTB launcher itself.
