I was taking a look at the logs, for safety, and I have found those logs below:
nori-hidamari kernel: [ 1829.683564] ecryptfs_decrypt_page: Error
attempting to read lower page; rc = [-4]
Apr 9 08:52:13 nori-hidamari
kernel: [ 1829.683569] ecryptfs_readpage: Error decrypting page; rc =
[-4]
ecryptfs probably has something with encryption, but what that log actually means?
Thank you guys for helping me.
