There are several threads concerning deactivating encryption by ecryptfs on a home directory. A selection is listed below. All (seem to) suggest that the current home directory will be wiped out by the process of removing encryption.
The output of
ecryptfs-setup-private --undo says
In the event that you want to remove your eCryptfs Private Directory setup, you will need to very carefully perform the following actions manually:
- Obtain your Private directory mountpoint $ PRIVATE=
cat ~/.ecryptfs/Private.mnt 2>/dev/null || echo $HOME/Private
- Ensure that you have moved all relevant data out of your
- Unmount your encrypted private directory
- Make your Private directory writable again
$ chmod 700 $PRIVATE
- Remove $PRIVATE, ~/.Private, ~/.ecryptfs Note: THIS IS VERY PERMANENT, BE VERY CAREFUL
$ rm -rf $PRIVATE ~/.Private ~/.ecryptfs
- Uninstall the utilities (this is specific to your Linux distribution)
$ sudo apt-get remove ecryptfs-utils libecryptfs0
$PRIVATE is actually
/home/user (the directory protected by encryption, please check), the current home directory gets emptied and deleted because of one's own doing through
rm -rf $PRIVATE
I noticed one fellow's interesting remark on line 5. Reportedly https://askubuntu.com/a/10049/446253 did not find deleting home necessary, which is a very interesting hint. Making back-ups of data is good in its own right, but it's no immaterial thing if you could remove encryption without manipulating your user home content!
I am not certainly asking to put your own data at risk in place of mine, but could more experienced people judge whether a step 5 like
rm -rf ~/.Private ~/.ecryptfs would be sufficient instead?
This could help out people who struggle with full disks to be emptied and cannot resort to network file systems because of encryption, for example.
