You have issues with the perms. What user are you using to run the command bench update?
See if this can help: File and folder Permissions

Or you can type in the console ll -h to see who is the owner of the frappe apps folders (also files and subfolders recursively) and then logging in with that user and password to the operating system.

thanks I’ll try that

found out some of the folders belong to root. So I change owner of /home/frappe/.bench to frappe with the command chown -R frappe:frappe /home/frappe/.bench. after that login as frappe user and run bench update --upgrade.
Solved the perm problem.

Thanks
