xargs rm < install_manifest.txt

install_manifest.txt is created when you run make install.

If you have missing files, or any discrepancies between physical and virtual filesystem under NextCloud, do this:

Go to the root directory of the NexctCloud installation, the issue the command (use webserver's owner as user, here: www):

 sudo -u www php ./occ files:scan --all

# cd /etc/bind

Add these lines to your zone declaration in named.conf.local:

inline-signing yes;
auto-dnssec maintain;

Then:

# mkdir /etc/bind/zones
# cd /etc/bind/zones

  Here, create your zone file: example.com.db

To switch this off put something like below into your ~/.jedrc file:

WRAP_DEFAULT=2048

Now line wrapping is performed at the 2048th character.
