There is a critical
rpm-ostreeregression in version 2026.1 causing upgrade failures. To confirm whether you are on the impacted version, checkrpm-ostree --version. If the version shows 2026.1, follow these mitigation steps verbatim, allowing you to bypass the regression and resume upgrades to thelatesttag, wherein the issue has already been mitigated by pinning the previousrpm-ostreeversion:
$ run0
# rpm-ostree usroverlay
# dnf5 install -y --from-repo=updates-archive rpm-ostree-2025.12-1.fc43
# ujust update-system
# systemctl reboot
We will be working with upstream to help close the gap in continuous integration coverage that allowed this regression to ship.
