When I want to install a package or do an apt-get update, the system returns an error like (read-only file system) can you help me please. I have Raspbian Stretch Lite.
I did not download other packages because I can not install anything on the system.
sudo apt-get update
Error messages are like:
Err 3: mirrordirector.rasbian.org/debian streatch Release open (30: Read-only file system) Could not create temporary file to work with
