  interpreter: Permission denied--: /usr/share/l.v.e-manager/utils/cloudlinux-cli.py: Success

Environment

• CloudLinux
• cPanel

Solution

The CloudLinux Python interpreter has no execute permission:

/opt/alt/python311/bin/python3.11 → was 0644 (rw-r--r--), should be 0755 (rwxr-xr-x)

To work it out, set the proper permissions with this command:

chmod 0755 /opt/alt/python311/bin/python3.11
