Proceeding pro se, Christopher Shawn Collier, federal prisoner # 10070-180, appeals the dismissal, for lack of jurisdiction, of his 28 U.S.C. § 2241 petition. Collier challenges his 360-month sentence imposed following his conviction in 2002 of conspiracy to possess with intent to distribute 50 grams of methamphetamine and possession of methamphetamine, in violation of 21 U.S.C. §§ 841 and 846.

Pro se briefs are afforded liberal construction. Yohey v. Collins, 985 F.2d 222, 225 (5th Cir. 1993). Nevertheless, the failure to identify any error in the district court’s analysis is the same as if the appellant had not appealed the. issue. Brinkmann v. Dallas Cty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Because Collier fails to challenge the district court’s dismissal of his § 2241 petition for lack of jurisdiction, he has abandoned the critical issue of this appeal.

AFFIRMED.
