Description Marcel Haerry 2025-12-29 16:24:17 UTC

As reported here https://github.com/evilsocket/opensnitch/issues/1486 if RPMs are compressed using zstd you are currently unable to layer them using rpm-ostree install:


$ rpm-ostree install opensnitch-ui-1.8.0-1.noarch.rpm
error: Reading rpm2cpio: Unrecognized archive format

Fedora should fully support zstd compressed RPMs: https://fedoraproject.org/wiki/Changes/Switch_RPMs_to_zstd_compression However it looks like the rpm2cpio within rpm-ostree is not able to do so.

Reproducible: Always

Steps to Reproduce:
1. try to install https://github.com/evilsocket/opensnitch the ui RPM and fail
