Sources say Bono is having trouble penning lyrics for new album.

Bono still hasn’t found what he’s looking for.

What was supposed to have been another big year for supergroup U2 will have to wait. And Confidenti@l sources say the roadblock is in their front man’s head.

“Bono’s had trouble writing songs for the new album,” says one insider close to the band.

U2 hoped to release a new album in the coming months, even though a date was never announced. Our spy says the plan was to follow that release with a tour at the end of the year. Neither of those things is likely to happen as scheduled and industry insiders say it’s because Bono is struggling to pen new lyrics.

“There’s no new music,” says a source “It’s easy to release a song, but not an album.”

A second source close to the band says, “It’s as simple as this — the album isn’t done.”

Billboard magazine reported earlier this month that U2’s new album would be pushed back until 2015, with one source stating, “That magic that the band always seems to capture ... they have yet to capture it.”

Our second source says the band is still expecting to release a new album this year and that the tour was likely to start in 2015 either way.

U2 certainly started 2014 like a band with something to promote. After winning a Golden Globe in January, they performed on the debut of NBC’s “The Tonight Show Starring Jimmy Fallon.” They also rocked the Academy Awards earlier this month, playing their Oscar-nominated song “Ordinary Love,” their first new tune in three years.

Both our insiders insist that delays in the studio should not be mistaken for disharmony in the band.

“No, no, no,” our first spy assures us. “It’s nothing like that — at all!”

Though U2’s first eight studio albums came within a 13-year span, the four that followed were an average of four years apart. The band’s last album, “No Line on the Horizon,” is more than five years old.

Our source also says that the band’s split with Paul McGuinness, their manager of 35 years, and decision to sign with manager Guy Oseary last November weren’t connected to problems with the new project. In December, the group’s website reported that “sometime soon, U2 will begin a new adventure around the world and we totally understand and respect Paul’s desire to not run away with the circus — AGAIN.”

Hopefully for U2 fans, the band’s ringleader will get the show on the road sooner than later.
