Download logs fails with error 500 and apache does not start


Issue:
Trying to download logs from the UI fails with error 500 


And apache logs showing permission error in /var/log/apache2/error.log (need to run sudo su command to access folder/file)
[Sun Jan 08 06:25:58.075748 2023] [wsgi:error] [pid 27795:tid 140300522448640] [client 127.0.0.1:33668] PermissionError: [Errno 13] Permission denied: '/var/log/cpm/cpm_server.log'

In addition, During server restart apache might not start.

Solution:
connect to cpm over SSH using cpmuser and your key.
run the following command: sudo chown -R  www-data:www-data /var/log/cpm
After this log download should work and the apache server will start correctly.
