I just upgraded my ubuntu to 17.10. The process of upgrade was very smooth.
Then, I ran into a very strange permission problem.
I use a synology NAS and mount nfs to that NAS regularly.
However, after I upgraded to 17.10, all the GUI applications only can access the mounted directory read only.
Let me repeat this:
all GUI applications, such as nemo / nautilus or any application that requires file access, are read-only, while my terminal can read/write without problem: rm, mv, etc.
I suspect Ubuntu 17.10 did something differently than 17.04. but at this point i have no idea where to look for solution.
any hint will be much appreciate.
Because i am using a laptop, I don’t put mount point at /etc/fstab. I mount it by issue a command
sudo mount -t nfs 192.168.1.23:/volume1/download /media/user/nas/download
this worked without issue in the past.
Since this is not a pure permission issue, nor does it produce any error message anywhere, I am stuck.
Both Xorg and Wayland has this problem.
