There are three creditors, ECB, EU and IWF.
IWF by its very constitution is prohibited to forgive debt and ECB just as much.
The second salvage program (of 2012 thru then ESFS) is dead. Prematurely. Greece rejected it, first by walking out and then thru the referendum.
It'll be applying (or already has) for a third package and that has to go via ESM, ESFS's successor.

The term "bailout" that weakypedia uses is misleading. We're talking of loans here.
We're talking of aid that goes further into the future as opposed to til November (as with the rejected and prematurely killed package). That means impositions will be greater.
Of course we can get the EU chucking all regulations and laws and write new ones. But while the current ones are in place and honored, it takes 85 pct of all those having ratified the ESM to agree to giving aid (loans, as yet).
Germany has a veto right.
The ECB is prolonging the currently running ELA but it's capped at around 89 bn and analysts think it will run out any minute (Greece cashless). On its own it cannot and will not grant anything further.
Not with every country but with important ones (as in "clouty" like Germany) any negotiated deal will have to pass parliament. I'm not holding my breath.
Those are the facts.
