sftpgo project sftpgo UPGRADE

Affected: >= 2.3.0 and < 2.7.1

Fixed in: 2.7.1

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 2.3.0 (Debian / Ubuntu)

apt-cache madison sftpgo sudo apt install sftpgo=<VERSION_BEFORE_2.3.0> sudo apt-mark hold sftpgo

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.
