Troubleshoot issues where Linux cannot use chmod to change permissions

I installed the WIN10 and Ubuntu dual system, found in Ubuntu mount Windows hard disk without the command chmod change the permissions of the file, the workaround is logged as follows:

For an issue that uses the command $ chmod 777 dirname cannot change permissions.

1.lsattr-a View the permissions of all the files in the current directory, determine if the file permissions you want to change have I, as follows:

-------------e--./.gnome
---i------------./. IntelliJIdea2016.1
-------------e--./.mozilla
-------------e--./.dbeaver
-------------e--./.gksu.lock
-------------e--./.xsession-errors

File. IntelliJIdea2016.1 has permission I lock, next unlock

2,chattr-i . IntelliJIdea2016.1 Remove the I permission from the file (believe that you can then change the file permissions using chmod).

If Lsattr does not find the word "I", then there is another case where the NTFS system you are using is mounted without using the command. Use the following command:

sudo mount-t ntfs-o rw,auto,user,fmask=0022,dmask=0000,exec/dev/sda6/media/rjh/work/
