apt-cache madison nugetgallery sudo apt install nugetgallery=<VERSION_BEFORE_2024.06.21> sudo apt-mark hold nugetgallery

dnf --showduplicates list nugetgallery sudo dnf downgrade nugetgallery-<VERSION_BEFORE_2024.06.21> sudo dnf versionlock add nugetgallery

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
