We value your experience with Plesk during 2025 Plesk strives to perform even better in 2026. To help us improve further, please answer a few questions about your experience with Plesk Obsidian 2025. Please take this short survey: https://survey.webpros.com/
This is for Plesk Installer only, i.e. for downloading system packages. AFAIK, Extension Catalog packages do not support downloading over proxy.
But you could probably set up some transparent proxy by doing some iptables magic. I'm not going to provide specific instructions here.
plesk installer has the following relevant options (from --help-options):
Download options:
--source <URL or absolute path>
Installation source: a mirror URL or an absolute path
to a directory containing top-level products.inf3 file...
xmlrpc extension is no longer available (upstream discontinued its support).
ionCube loader extension is not available yet (no version compatible with PHP 8).
imagick extension is not available yet (no version compatible with PHP 8).
Check the article Igor posted above. If the last symptom is not present, this might be a previously unknown issue, in which case you're advised to address Plesk support.
To update to the latest Obsidian you may run:
plesk installer upgrade plesk release
To install the latest update in scope of the same 3-digit version:
plesk installer update
Updating to next versions on unsupported OSes (such as Debian 8, which has reached EOL) is unsurprisingly not possible.
Sorry, but no.
If you wish to have a customized phpMyAdmin installation (including any supported PHP version), you are free to install it manually on a domain. However, among other things you'll loose functionality of automatic login from Plesk.
The issue happens only on very specific setups (e.g. with specific Docker images running), so looks like it should be relatively rare.
The workaround will be automatically reverted on the next update, so no extra actions should be needed.
Your target server uses Debian 8, which is not supported by Plesk anymore (so no new versions). See also Feature Deprecation Plan
I suggest using a more modern OS supported by Plesk, such as Debian 10 or 9.
FYI: the issue is confirmed as PPPM-12387 and will be fixed in 18.0.31. Until then, if you're affected, it is sufficient to use the provided workaround.
It's slightly weird that a restart was required.
Anyway, the message means that your phpMyAdmin installation now operates without configuration storage (settings will not be saved on server side, only in your cookies), unless you've already addressed this somehow. The message explains why this...
Those that had a problem and restarting sw-cp-server service helped, could you post your OS, please? Did you have any errors or warnings on update to 18.0.30 (at least in /var/log/plesk/install/autoinstaller3.log)?
