Customer is attempting to install or upgrade Admin UI.
In the adminUI installation log you get the following errors,
FATAL ERROR - Command failed: Invoking Framework Installer\nReturn Value: 1\nStdout: Preparing SILENT Mode Installation...
AND / OR
\nStderr: CyberArk Privileged Session Manager X11 proxy: Authorisation not recognised
Release : 12.8
Installation is being done as a user (not root).
The user that is used to do the install has a disk space quota.
Check the user's home directory (i.e. /home/smuser) and run "df ." to check available space.
The available space required is 2gb.
The quote for the user needs to be removed or increased beyond 2gb.
Or perform the install with another user without a quota.
