- Plesk for Linux
Unable to upgrade Plesk to Obsidian on a Google Cloud instance:
when upgrading via Tools & Settings > Updates and Upgrades > Install or Upgrade Product, the following error message appears:
PLESK_ERROR: Unable to obtain the required version of Plesk Installer: The required version '3.23.20' was not found on the server. This could happen because of configuration error at the installation source. Version is not specified. Error in Version.cpp.
when upgrading via a command-line interface:
CONFIG_TEXT: *** Error in `/var/cache/parallels_installer/installer': free(): invalid pointer: 0x00007f402dd81bc0 ***
======= Backtrace: =========
Plesk Installer 3.23.20 crashes due to a library conflict with Google OS Login.
This is a Plesk bug with ID PPPM-11220, which will be fixed in future product updates.
As a workaround, apply one of the following solutions:
Perform the upgrade via a command-line interface without updating Plesk Installer:
Connect to the Plesk server via SSH.
Run Plesk Installer using this command:
# plesk installer --disable-self-upgrade
