linux - ubuntu backup-manager Permission denied -

-

i've installed backup manager onto ubuntu machine have automated backup going. problem when go set automatization using code -

code

it comes saying "bash: /etc/backup-manager.sh: permission denied"

i not understand error. i've tried change user read/writes other root , didn't work. tried changed chmod number 770 700 , still didn't work.

enter image description here

any info on welcome. thank :) wondering using tutorial giving me host. https://documentation.online.net/en/dedicated-server/tutorials/backup/configure-backup/start

i'm using desktop version of ubuntu 16 incase needed

the sudo doesn't want in case. happens shell evaluates redirection , attempts open /etc/backup-manager.sh before sudo cat gets started. fails because shell still runs unprivileged user. have sudo -i open new root shell, execute commands , exit again. alternatively try sudo nano /etc/backup-manager.sh , paste contents there. work because editor run root , file opening when save.
