I want to delete/replace a file in my /opt folder.
However, it says "files sytem is read only"
I checked /etc/mtab output, saw that only ubi0:rootfs file system is read only. How can I delete/replace file in /opt folder? I tried to remount file system but no luck.



This is my /etc/mtab output



~$ more /etc/mtab
