pgadmin pgadmin 4 UPGRADE

Affected: >= 9.4 and < 9.15

Fixed in: 9.15

Safe to downgrade to: a release before 9.4

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 9.4 (Debian / Ubuntu)

apt-cache madison pgadmin-4 sudo apt install pgadmin-4=<VERSION_BEFORE_9.4> sudo apt-mark hold pgadmin-4

dnf --showduplicates list pgadmin-4 sudo dnf downgrade pgadmin-4-<VERSION_BEFORE_9.4> sudo dnf versionlock add pgadmin-4

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.
