Hi Hannah,
Glad to hear that! I don’t really see it as a problem with Ghost per se; logrotate is a standard utility that most Linux sysadmins would be aware of that might need configuration with the installation of a new application. The only reason I brought it up to the community is that others may not be aware.
Looks like I’m not the first person to notice this, someone else reported it here back in October:
Install process was about 1.5-2 yrs ago using the following guide for Ubuntu:
All defaults used, running Ubuntu 18.04 LTS with regular, weekly Ghost updates.
head -1 indicates the access log in /var/www/ghost/content/logs/ goes back to June 2020.
