"Solutions - 3 Methods to Resolve 'Can't Open File for Writing' Error in Vim"

E212: Can't open file for writing is an error that may occur when attempting to save a file in Vim. This issue can stem from several causes, and there are various methods to resolve it.

Method 1: Validate User and Check File Permissions

The root cause of the error typically lies in permission issues. The solution is to prefix the command with 'sudo' which temporarily grants administrative privileges when using the 'vi' command to open the file. For instance, you would use the command "sudo vi hosts" to open and edit the file. This allows you to have the necessary permissions to manipulate the file.

Step 1. Edit the "sources.list" file using a non-root user with the following command.

$ vim /etc/apt/sources.list

Step 2. Encounter the error "E212: Can't open file for writing" while trying to access "/etc/apt/sources.list".

Step 3. Run sudo permissions to fix the error. This means: "Execute the command 'sudo' to fix the permission error."

$ sudo vim /etc/apt/sources.list

Method 2: Check if the File is Locked to Resolve "Can't Open File for Writing"

If you are a root or sudo user and still cannot open the file for writing, try exiting the file and check if the "I" command has locked it.

Step 1. Locate the file using this command:

lsattr /home/admin/$filename

Step 2. Check the I lock.

If an "I" is displayed, the file is locked. You can run this command to unlock your files.

chattr -i $filename

After this, type `q!` to exit the file. Upon viewing the file again, you'll notice that the content has been modified and saved.

Method 3: Check for Read-only File System or Capacity Issue

You may still encounter this error even if you have the necessary permissions and use the sudo command. In such a case, you should inspect for a read-only file system or a capacity issue.

Step 1. Check the disk space using this command.

Run the command: ```bash df -h ```

Step 2. Next, free up space by deleting or removing unnecessary files using the `rm` command.

Step 3. Run the mount command to check for your device. It should be mounted as read-write (rw), not read-only (ro).

$ mount translates to "mount" in English. This is a command used in Unix-based systems to attach a file system to a directory in the current file hierarchy.

Step 4. Correct any file system errors and remount it as a read-write file system.

After that, you should have resolved the "E212: Vim cannot open file for writing" error. If you're still encountering issues, you can refer to this video for further assistance.
