You can, as vi (or, more likely, vim ) is saying force a write by doing:

Alternatively, write the file to an alternative location:

To check where your backup files are being written (normally):

Try to touch a file in that directory and see if your Operating System gives you an error to enlighten you as to why your editor cannot write there.

/.vim/backups ) didn’t exist. I created it, and the error went away. – Sheharyar Jan 10 ’15 at 20:29

/.vim/ directory. – Cbhihe Mar 20 ’16 at 13:30

/.vimbackup are owned by root. Changing owner back to me solves the problems. sudo chown -R peng:peng

/tmp and didn’t exist. Creating it solved the issue. – mike23 Jun 27 at 6:49

Had the same problem. It was because I installed vimconf as root. You need to change rights of files in

/.vim directory and change owner to your user.

) wasn’t writeable anymore. Not sure how that happened, I don’t remember chmodding anything. – Michele Dall’Agata Mar 21 ’18 at 10:08

I had this same problem. Turns out it was due to running out of disk space. try creating a file using Ex) touch test.txt . If you get a message saying touch: cannot touch test.txt: No space left on device you will need to clear up space on your disk

Had the same problem. Tried all options as above but it did not work. Then when I checked my disk space, it was full. Once I cleared some space then I was able to write back to file again.
P.S: This was in linux.

I’ve fixed this with:

where the "user" is your user-name.

from within vi, try:

:help w! gives the following information:

I don’t know what the cause was, but I moved by backupdir from . to

/.vim/backups in my .vimrc and it solved it for me:

I’d imagine some sort of tool was using the folder the file I was editing it in (Visual Studio 2013, in my case), but I’m not sure.

Another possibility is that you put your backups in a centralized location (e.g. /tmp) and you edited a particular file as root. Then, the backup file will be owned by root and un-writeable by you as a mere mortal later.

In this case, the suggestion above to touch /tmp/atestfile won’t show the problem! You’ll have write permissions, no problem, but not to the particular backup file vim is trying to write.

Remove the file as root (sudo rm).

Note that the reason w! works is because vim writes the file without writing a backup file (you’re insisting that it write despite the error).

I have downloaded the second episode of the “The Tyranny of King Washington-The Betrayal”, but when I try to install, It states that I need to update the Assassin’s Creed 3 to version 1.0.4. I have tried updating it but when I open the updater, an error message comes up showing that it couldn’t backup the file ‘C:Program FilesAssasin’s Creed 3Multi.forge’. Please help me out with this. I have tried all means but nothing worked. Please help me because I am a die-hard fan of AC series and desperately want to know the story in the DLC. Thank you in advance.
