1) I set up JTable with setAutoCreateRowSorter(true) so that all tables can be sorted by clicking on the column headers. However, I want to exclude some tables from this, but when I try using table.setAutoCreateRowSorter(false), it doesn't work at all.
Solution:
Disable the table header with table.getTableHeader().setEnabled(false);

1)   HTTP_OC_CHUCKED OC_Chunked header "is allowed only in webdav endpoint owncloud". 
This happen when after set env OWNCLOUD_CHUNKING_NG=0  ?
revert that OWNCLOUD_CHUNKING_NG to OWNCLOUD_CHUNKING_NG=1 or just remove it.

2)   Connection Closed 
Only works for files below 100mb?
set environment variable OWNCLOUD_MAX_CHUNK_SIZE
e.g :
OWNCLOUD_MAX_CHUNK_SIZE=10737418240 ; for 10GB (default 100000000 or 100MB)

Just Self Note:

1 ) turn on maintenance mode (in owncloud folder)
    sudo -u www-data php occ maintenance:mode --on

2)  turn off apache2 service 
    sudo systemctl stop apache2

3)  rename/move previous owncloud folder to another
    sudo mv owncloud owncloud_backup
