Tommy Alexander, Sr., federal prisoner # 07193-035, appeals the dismissal of a “Petition and Motion for a Writ of Coram Nobis and/or Audita Querela,” alleging that his conviction was based on an illegal search, fabricated evidence, and prosecuto-rial misconduct and that relief under the All Writs Act is necessary to correct manifest injustice and fundamental constitutional error. He argues that the district court did not provide adequate reasons for the dismissal and it erred by failing to address the merits of his arguments. The Government has moved for dismissal of the appeal, summary affirmance, or an extension of time to brief the merits.

Alexander, who remains incarcerated, is not eligible for coram nobis relief. See United States v. Esogbue, 357 F.3d 532, 534 (5th Cir. 2004) Alexander’s pleading challenged his federal sentence and is therefore a motion under 28 U.S.C. § 2255. The district court lacked jurisdiction because Alexander has previously filed a § 2255 motion, and we have not authorized him to file a successive motion. See Hooker v. Sivley, 187 F.3d 680, 681-82 (5th Cir. 1999). As the appeal is utterly without merit, the motion to dismiss is GRANTED and the appeal is DISMISSED. Howard v. King, 707 F.2d 215, 219-20 (5th Cir. 1983); see 5th Cir. R. 42.2. *468 The Government’s alternative motions for summary affirmance or an extension of time to brief the merits are DENIED. We CAUTION Alexander that future frivolous filings may result in the imposition of sanctions.
