UberStudent Forums

After opening Update Man and Refresh I cannot install.
Respectfully request help, please.

That error of "Error creating textual authentication agent" suggests that uberstudentupdate is not running with administrative privileges. Does launching uberstudentupdate via the command "sudo uberstudentupdate" (no quotes) enable the installation of updates without errors?

Thank you, Damion. Success.
Previously Update Manager worked fine, then it just stalled after Refresh completed and upon clicking Install it gave a quick screen flash and nothing more. I can update via command now.
