Are you sure you are actually root? Ubuntu disables the root account by default so you can't login as root unless you have made changes. Run id to determine which user you are. If you are not root you can become root by running sudo su - or run any command as root by using sudo. Use gksudo if you need to run gui applications as root.

Does root have write permissions for the parent directory?

Does root have write permissions for the parent directory?
Not really important. root always has write permissions. Even when you specifically say root does not have write permissions it still does. Programs that check for permissions like vi will say that the file is read only but you can still force a write if you are root.

Did you by any chance change file attributes?

man lsattr
man chattr

Hello guys,

Sorry the issue was because of "system corruption" so as you know when that case occur you cannot do anything, so the system protect itself and no one can edit files nor create new ons. .... ;):lolflag:

The real issue is when there is a lot of errors on the file system (ext3 fs) there is option on the mount is "errors=remount-ro" which will remount the file system in read only mode
and thats it, so the solution maybe will be remount it with r/w mode (but I didnt test it so i dont recommond that except in case that you dont have any other solution) normally the solution is reinstall the os but of course after you backup your data.
