nginx update broke pikrellcam #40

Closed okazou57 closed 5 years ago

okazou57 commented 5 years ago

On november 11 I did an update to my raspbian, it consisted mostly of nginx updates. After that update, pikrellcam stoped working an I get the following message in journalctl when I try to start pikrellcam from the web interface: Nov 21 14:17:53 RPi-Salon sudo[1468]: www-data : TTY=unknown ; PWD=/home/pi/pikrellcam/www ; USER=pi ; COMMAND=/home/pi/pikrellcam/pikrellcam Nov 21 14:17:53 RPi-Salon sudo[1468]: pam_unix(sudo:session): session opened for user pi by (uid=0) Nov 21 14:17:53 RPi-Salon sudo[1492]: pam_unix(sudo:auth): conversation failed

I have been checking all permissions and made shure pi was member of www-data group, nothing worked any indication as to where I should be looking for?

The web interface runs as user www-data and needs sudo permission to run pikrellcam. The error you get seems to say www-data fails trying to do that.

1) can you run pikrellcam by hand from a terminal as user pi? Just enter the "pikrellcam" command.

2) do you still have the file /etc/sudoers.d/pikrellcam with the line: www-data ALL=(pi) NOPASSWD: /home/pi/pikrellcam/pikrellcam

If not, try a rerun of the pikrellcam install script.

Thanks a lot!!! I did not have the www-data ALL=(pi) NOPASSWD: /home/pi/pikrellcam/pikrellcam in my sudoer file. I do not remember seeing that at any time. Most likely not caused by the nginx update. Every thing back to normal.
