atom electron UPGRADE

Affected: >= 1.6.4 and <= 1.6.11 · >= 1.7.0 and <= 1.7.5

Fixed in: newer than 1.7.5

Safe to downgrade to: a release before 1.6.4

1. Check installed version

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

2. UPGRADE to newer than 1.7.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade electron

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 1.6.4 (Debian / Ubuntu)

apt-cache madison electron sudo apt install electron=<VERSION_BEFORE_1.6.4> sudo apt-mark hold electron

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

dnf --showduplicates list electron sudo dnf downgrade electron-<VERSION_BEFORE_1.6.4> sudo dnf versionlock add electron

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.
