Solutions - 3 Ways to Fix Can't Open File for Writing in Vim

E212: can't open file for writing is an error that can occur when trying to save a file in Vim. There are a few different ways to fix this error, depending on the cause. 

Method 1. Validate User and Check File Permissions

The general cause of the error is the permission issue. The solution is to add sudo in front of the file to temporarily provide administrator privileges when using the vi command to open the file. For example, use the command "sudo vi hosts" to open and edit 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. Get "/etc/apt/sources.list" E212: Can't open file for writing" error.

Step 3. Run sudo permissions to fix the error.

$ sudo vim /etc/apt/sources.list

Method 2. Check If the File Is Locked to Fix Can't Open File for Writing

If you are a root or sudo user, but you still can't open the file for writing. Then, you can try to exit the file and check if the "I" command locks it.

Step 1. Find the file with this command:

lsattr /home/admin/$filename

Step 2. Check the I lock.

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

chattr -i $filename

After this, execute q! to exit the file. When viewing the file again, it is found that the content has been changed and saved.

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

You still face this error if you have permission and use the sudo command. Then, you need to check for a read-only file system or capacity issue.

Step 1. Check the disk space with this command.

$ df -h

Step 2. Then, make space by deleting or removing unnecessary files using the rm command.

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

$ mount

Step 4. Fix the file system errors and re-mount it to a read-write file system.

$ sudo mount -o remount,rw /partition/identifier /mount/point or $ sudo mount -o remount,rw /
