James Arthur Woodley, federal prisoner # 83958-079, seeks leave to appeal in for- *270 ma pauperis (IFP) from the dismissal of his 28 U.S.C. § 2241 petition. We will not grant the motion unless Woodley shows that he has at least one nonfrivolous appellate claim and thus is taking the appeal in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997). Our inquiry into an appellant’s good faith “is limited to whether the appeal involves legal points arguable on their merits (and therefore not frivolous).” Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983) (internal quotation marks and citation omitted). Woodley has not met this standard.

Woodley has shown no error in the district court’s reasoning and thus has not shown that he has a nonfrivolous appellate claim. Because the claims raised in his § 2241 petition concern his conviction and sentence, rather than the manner in which his sentence is being executed, they arise under 28 U.S.C. § 2255, not § 2241. See Tolliver v. Dobre, 211 F.3d 876, 877 (5th Cir. 2000); Reyes-Requena v. United States, 243 F.3d 893, 900 (5th Cir. 2001). Additionally, he has not shown that he is entitled to proceed under the savings clause of § 2255(e), as he has not cited a retroactively applicable Supreme Court case showing that he was convicted of a nonexistent offense, See Reyes-Requena, 243 F.3d at 904. Because he has not raised a viable § 2241 claim, there is no error in the denial of his motion for appointed counsel. See 18 U.S.C. § 3006A(a)(2)(B).

In sum, Woodley has failed to raise a nonfrivolous appellate claim. Accordingly, his motion to proceed IFP on appeal is DENIED. Because this appeal is frivolous, it is DISMISSED. See Baugh, 117 F.3d at 202 & n.24; 5th Cir. R. 42.2
