PER CURIAM:

Stanley Robinson, federal prisoner # 25071-044, moves for leave to proceed in forma pauperis (IFP) in this appeal from the dismissal of his 28 U.S.C. § 2241 petition. In his petition, Robinson challenged the sentence imposed following his conviction in 1998- in the Eastern District, of Missouri of possession of cocaine with intent to distribute, of using a firearm during and in relation to a drug trafficking crime, and of being a felon in possession of a firearm. Robinson contends that he should be permitted to proceed under the savings clause of 28 U.S.C. § 2255.

We have construed Robinson’s motion as a challenge to the district court’s determination that his appeal has not been brought, in good faith. *See Baugh v. Taylor,*117 F.3d 197, 202 (5th Cir.1997). Our inquiry “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 citations omitted).

Section 2255 provides “the primary means of collaterally attacking a federal sentence.” *Tolliver v. Dobre,*211 F.3d 876, 877 (5th Cir.2000). Section 2241, on' the other hand, is used to challenge “the manner in which a sentence is executed.” *Id.*A petition filed under § 2241 that raises errors that occurred at or prior to sentencing should be construed as a § 2255 motion. *Id.*at 877-78. However, under the savings clause, a § 2241 petition that attacks custody resulting from a fed*477erally imposed sentence may be entertained if the petitioner shows that the remedy provided under § 2255 is inadequate or ineffective to test the legality of his detention. *Jeffers v. Chandler,*253 F.3d 827, 830 (5th Cir.2001); *see also*§ 2255(e).

Robinson has the burden of showing that the § 2255 remedy is inadequate or ineffective. *See Wesson v. United States Penitentiary Beaumont, TX,*305 F.3d 343, 347 (5th Cir.2002). He must show that his claims are “based on a retroactively applicable Supreme Court decision which establishes that the petitioner may have been convicted of a nonexistent offense” and were “foreclosed by circuit law at the time when the claim[s] should have been raised in [his] trial, appeal, or first § 2255 motion.” *Reyes-Requena v. United States,*243 F.3d 893, 904 (5th Cir.2001); see *also Jeffers,*253 F.3d at 830-31.

Robinson wishes to challenge the legality of his sentence based on the reasoning of *Apprendi v. New Jersey,*530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000); *Blakely v. Washington,*542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004); *Al-leyne v. United States,*— U.S.-, 133 S.Ct. 2151, 186 L.Ed.2d 314 (2013); and *Persaud v. United States,*— U.S. -, 134 S.Ct. 1023, 188 L.Ed.2d 117 (2014). His invocation of *Apprendi, Blakely,*and *Alleyne,*is predicated on his contention that *Persaud*announced a change in the law. *Persaud*was not a substantive decision and, therefore, does not support Robinson’s contention that the particular sentencing errors he complains of are amenable to § 2241 relief in this case.

The request for leave to proceed IFP on appeal is DENIED, and the appeal is DISMISSED. *See Baugh v. Taylor,*117 F.3d 197, 202 n. 24; *see also*5th Cir. R. 42.2.
