• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

/tmp installer bug

HostaHost

Silver Pleskian
If /tmp doesn't have permissions 1777 installation will fail since the installer does not bother to check if the permissions necessary to complete install are present even though someone took the time to add in a nice error message telling you your permissions are not comptaible with the install:

Code:
/tmp should have at least 777 file access permissions.
Run 'chmod 1777 /tmp' as root to set up proper file access permissions.


**** Product prep-install failed.

*****  problem report *****
/tmp should have at least 777 file access permissions.
Run 'chmod 1777 /tmp' as root to set up proper file access permissions.


ERROR: An error occurred during performing of installation PREP actions (see log for details). Installation was rolled back.
Warning! Not all packages were installed.
Please check if your system services are operable.
Please resolve this issue and try installing the packages again.
If you cannot resolve the issue on your own, contact product technical support for assistance.

So of course at this point the install has already modified a bunch of the config files on the server, who knows what has been completed and has not been completed, and if my experience with plesk is any indicator, better to just wipe the whole server out and start over since a failed install now tends to result in nightmare upgrades later.

My suggestion would be to check for these things in advance instead of after already installing half the packages.
