sbackup tar fails on Ubuntu 18.04 and xubuntu 18.10

[Doug Shelton]

OS xubuntu 18.10
sbackup version 0.11.6
installed from synaptic package manager main repository

/bin/tar: The following options were used after any non-optional arguments in archive create or update mode. These options are positional and affect only arguments that follow them. Please, rearrange them properly.
/bin/tar: --exclude-from '/tmp/sbackup/excludes.list' has no effect
/

it looks like tar syntax has changed so "--exclude-from" no longer works.

[Doug Shelton (dshelton-san)]

this issue is caused by a change in behavior in tar 1.3, wherein it sets the exit code "2" when positional arguments are used out of order.

The fix to this problem is to modify /ar_backend/tar.py. Change

    options.append('--files-from=%s' % tmp_incl)
    options.append('--exclude-from=%s' % tmp_excl)

to

    options.append('--exclude-from=%s' % tmp_excl)
    options.append('--files-from=%s' % tmp_incl)

Described solution #2 works for me. Thank you.
