adobe photoshop UPGRADE

Affected: >= 27.0 and < 27.5

Fixed in: 27.5

Safe to downgrade to: a release before 27.0

1. Check installed version

apt-cache policy photoshop || rpm -q photoshop || photoshop --version

2. UPGRADE to 27.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade photoshop

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade photoshop

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 27.0 (Debian / Ubuntu)

apt-cache madison photoshop sudo apt install photoshop=<VERSION_BEFORE_27.0> sudo apt-mark hold photoshop

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

dnf --showduplicates list photoshop sudo dnf downgrade photoshop-<VERSION_BEFORE_27.0> sudo dnf versionlock add photoshop

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.
