microsoft visual studio code UPGRADE

Affected: >= 1.0.0 and < 1.128.1

Fixed in: 1.128.1

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy visual-studio-code || rpm -q visual-studio-code || visual-studio-code --version

2. UPGRADE to 1.128.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade visual-studio-code

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade visual-studio-code

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 1.0.0 (Debian / Ubuntu)

apt-cache madison visual-studio-code sudo apt install visual-studio-code=<VERSION_BEFORE_1.0.0> sudo apt-mark hold visual-studio-code

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

dnf --showduplicates list visual-studio-code sudo dnf downgrade visual-studio-code-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add visual-studio-code

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.
