symantec reporter UPGRADE

Affected: >= 9.5 and < 9.5.4.1 · 10.1

Fixed in: 9.5.4.1

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 9.5 (Debian / Ubuntu)

apt-cache madison reporter sudo apt install reporter=<VERSION_BEFORE_9.5> sudo apt-mark hold reporter

dnf --showduplicates list reporter sudo dnf downgrade reporter-<VERSION_BEFORE_9.5> sudo dnf versionlock add reporter

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.
