unable to delete file - rm: cannot remove Input/output error
Solution 1:
The same circumstance I met. I am pretty sure I am going to delete the directory. So I try to use rm -rf XXX and also Shift + Delete to remove but both failed because of the same error. Interestingly, I fixed it by right clicking the directory Move to Trash and then Empty Trash. Hope works for you too.
Solution 2:
Looks like the filesystem has some errors on it. Do full scandisk /checkdisk from windows. (scan disk for errors)
