A new batch of Glastonbury tickets went on sale on Thursday - but sold out within the same day.
Fewer than 1,000 tickets went on sale because some fans accidentally ordered too many when they first went on sale, but were ineligible to receive them.
All 112,000 tickets were thought to have been snapped up within a day when they were originally released.
Festival organiser Michael Eavis has now suggested selling next year's tickets by a lottery, according to NME.
On Thursday, ticket agency Aloud said hundreds of "duplicate" tickets were put back on sale and sold out within about two hours.
"
The high tech approach, the website and all that, it's all too big

A message appeared on the official Glastonbury site on Thursday saying: "Due to reallocation of duplicate tickets a limited number of Festival tickets are now available."
On 1 April, three million phone calls were logged by people trying to buy tickets, with some 200 million redials.
And the Aloud website got two million impressions in the first five minutes of tickets going on sale, Aloud said.
This year's festival takes place between 25-27 June, and features headline performances from Sir Paul McCartney, Oasis and Muse.
'Tombola'
Festival organiser Michael Eavis has admitted they were overwhelmed by demand, but pledged improvements for the festival in 2005.
He told NME.com: "I just wonder whether the future is really low tech? Everybody writes in, we put the names in a big tombola and we pick 115,000 letters.
"I wonder whether that's the new approach we should consider. The high tech approach, the website and all that, it's all too big.
"Everybody gets on the websites and there's so many people out there. It seems to crash."
