17.10 NFS GUI write issue (terminal rw fine)

Dear all:

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.

Any idea?

Welcome to the Ubuntu Community Hub, however this is NOT a support site. please refer https://community.ubuntu.com/t/community-support/709

i grabbed a laptop i upgraded last weekend to (ubu-mate) 17.10; it doesn’t automount my nfs either (",noauto" is in my fstab), so I did a mount /directory & i could rw from term and gui without issues. but this isn’t the place for support.

I’ve moved this to the https://community.ubuntu.com/c/support-help-requests category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the https://community.ubuntu.com/t/finding-help/712 page.
