I had qBittorrent an Nzbget downloading things over SMB and it worked fine, after the 1.6 update on a Zimacube it stopped working due to wrong permissions if I rolled back to 1.4.6 it worked again; but I wanted the update so I tried with ChatGPT and after a lot of troubleshooting it helped me to fix /etc/fstab by doing the next steps on terminal:
Try with this line to change the permissions temporarily on SMB shared directory:
sudo mount -t cifs //10.10.1.10/Downloads /media/10.10.1.10/Downloads \
-o username=User,password='password',uid=1000,gid=1000,file_mode=0775,dir_mode=0775,vers=3.0,noperm
To make this permanent after a lot of troubleshooting now on Claude I got a script that I ran on terminal:
sudo tee /etc/systemd/system/fix-smb-permissions.service << 'EOF'

I had other issue where all my external drives changed their names like “ExternalDrive_1” and messed with my backups, to fix that I had to:
Lazy unmount the drives: sudo umount -l /dev/sda2
Unmount the old folder: sudo rm -r /media/ExternalDrive_1
Make a new directory: sudo mkdir /media/ExternalDrive
Remount the new drive: sudo mount /dev/sda2 /media/ExternalDrive
and make it permanent by editing /etc/fstab and adding this line:
LABEL=ExternalDrive /media/ExternalDrive exfat defaults,umask=0000,uid=1000,gid=1000 0 0
And remount using: sudo mount -a
And after all this troubleshooting i’m really wondering what happened with this update that messed with all the SMB shares and external drives.
