How to fix error message: EROFS: read-only file system

The error message says that your file system is read-only, which is not a Ghost issue.

I can see it from Ubuntu 22.04

You could try rebooting the server and reviewing the general server logs. I can’t think of anything that Ghost could do which could cause the file system to become read-only.

You could try asking at: They would want you to provide details of what has happened on the server, because it’s not normal for Ubuntu 22.04 to have a read-only filesystem.
