Permission denied during scraping #174

Closed acidrs03 closed 7 years ago

acidrs03 commented 7 years ago

Latest Retropie 4.2 install Scraper installed from optional packages in retropie-setup From the pi command line running the scraper configuration and choosing scrape all or scrape chosen systems i get permission denied errors my output example 2017/08/14 06:53:10 ERR: error processing /home/pi/RetroPie/roms/psx/Einhander (USA).cue: open /home/pi/RetroPie/roms/psx/images/Einhander (USA)-image.jpg: permission denied

Roms are located on a NAS system which could be the cause of the permissions issues.

Running /home/pi/RetroPie-Setup/retropie-setup.sh as sudo or under sudo su makes no difference.

The error is from not being able to write the file to disk. So I would check the permissions on the folder /home/pi/RetroPie/roms/psx/images.

Ok for the life of me i cannot change the permissions of the folders on m,y FreeNas to be able to overcome the Permission Denied message. From withiin RetroPie command line i can mkdir on the freeNas but changing permissions results in Operation not permitted etc. I have even gone into the FreeNas web gui and created a user pi and group pi and set it as the owner and owner group of the retropie Dataset with no luck.

Another Option i was thinking, would be to deselect the use rom folder to store images and gamelist and let it save them to the default location. This would remove the permission denied i am getting. Once all the data has been downloaded, could i them just move the images and gamelist files to their respective roms folders. If so, what file stores the path information for loading the image data. As i would have to edit this file to look for the images in the roms folder.

i have the same problem and none of my other devices connected to this share has any permission problems, however i noticed that when i run the scraper from cli with sudo, it works. so my guess is its something to do with the user, used to scrape. *edit: it seems i fixed the problem by forcing uid/gid for the user of the share, so in a way i was actually right ... however the problem lies is in the way the net share is mounted (another lesson in dont cut & paste i guess) and i think a few edit to the instructions on "Running-ROMs-from-a-Network-Share" would fix this problem for everyone.

I haven't tried this on my FreeNAS but there isn't a really anything my code can do. Like @Halvhjearne mentioned it could be the way the /etc/fstab is written and the default isn't allowing non-root write access.

I had this same issue,but found out that the optional scraper does not input password(most likely). I changed my share to mount as guest and bingo it works.
