$ sudo vim /etc/20230712_app_server.log [sudo] password for user: sudo: unable to open '/etc/20230712_app_server.log' Read-only file system
You need to first check if the mount status is not read-only.
# mount | grep /etc /dev/sda1 on /etc type ext4 (ro,relatime)
As you can see the mount is read-only!
Solution: In this case you can remount the filesystem.
# sudo mount -o remount,rw /dev/sda1 /etc
