I am facing an error while starting mailman core, it shows the following error:
$ mailman start Traceback (most recent call last): File "/usr/bin/mailman", line 11, in <module> load_entry_point('mailman==3.1.1', 'console_scripts', 'mailman')() File "/usr/lib/python3/dist-packages/mailman/bin/mailman.py", line 94, in main initialize(config_path) File "/usr/lib/python3/dist-packages/mailman/core/initialize.py", line 188, in initialize initialize_1(config_path) File "/usr/lib/python3/dist-packages/mailman/core/initialize.py", line 123, in initialize_1 mailman.config.config.load(config_path) File "/usr/lib/python3/dist-packages/mailman/config/config.py", line 106, in load with open(filename, 'r', encoding='utf-8') as user_config: PermissionError: [Errno 13] Permission denied: '/etc/mailman3/mailman.cfg'
Could anyone tell me how to I correct this error? Thanks.
