When trying to configure the auto changer in the API panel, I click. Checkbox
on get sudo configuration and when I test I get this error in red:
/usr/local/share/bacula/mtx-changer: mtx: not found
/usr/local/share/bacula/mtx-changer: perl: not found
Both mtx and perl are installed in the system , perhaps there’s a path issue
in the MTX changer script ?
