gnome gnome-maps UPGRADE

Affected: >= 43.0 and < 43.7 · >= 44.0 and < 44.4

Fixed in: 43.7, 44.4

Safe to downgrade to: a release before 43.0

1. Check installed version

apt-cache policy gnome-maps || rpm -q gnome-maps || gnome-maps --version

2. UPGRADE to 43.7 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade gnome-maps

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade gnome-maps

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 43.0 (Debian / Ubuntu)

apt-cache madison gnome-maps sudo apt install gnome-maps=<VERSION_BEFORE_43.0> sudo apt-mark hold gnome-maps

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gnome-maps sudo dnf downgrade gnome-maps-<VERSION_BEFORE_43.0> sudo dnf versionlock add gnome-maps

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.
