Terrence Doyle Mitchell, federal prisoner #04106-180, appeals from the district court’s order denying his motion for specific performance or reinstatement of his direct appeal. In his motion, Mitchell contended that his plea agreement was breached and that counsel was ineffective for failing to prosecute a direct appeal. Mitchell’s district court motion was an attempt to collaterally attack his sentence by raising errors that occurred at sentencing or during the period for pursuing a direct appeal. As such, the motion should have been construed by the district court as a 28 U.S.C. § 2255 motion. See Tolliver v. Dobre, 211 F.3d 876, 877 (5th Cir. 2000); see also United States v. Rich, 141 F.3d 550, 551 (5th Cir. 1998). Such a recharac-terization of Mitchell’s motion has important consequences of which Mitchell should be apprised. See Castro v. United States, 540 U.S. 375, 383, 124 S.Ct. 786, 157 L.Ed.2d 778 (2003). Also, because Mitchell’s motion was in the nature of a 2255 motion, we lack jurisdiction over his appeal absent ruling on a certificate of appealability in the district court. See United States v. Youngblood, 116 F.3d 1113, 1114-15 (5th Cir. 1997).

The judgment of the district court is VACATED and this case is REMANDED for further proceedings.
