Q: Ubuntu 18.04 mounted network shares not appearing under devices in file manager I am looking for a solution or some guidance on where to file a bug. 
On my 18.04 desktop installs (Gnome shell and Ubuntu Mate) when mounting network shares (SMB and NFS) they no longer appear under Devices in file manager (Nautilus or Caja), the mounts do succeed and are accessible at their mount points. 
In 16.04 and 17.10 these mounts appeared under Devices (

I am using the following code to mount NFS shares
sudo mount.nfs 192.168.2.123:/mnt/freenas-data1/photobackup /media/philroche/photobackup

and for SMB shares
sudo mount.cifs //192.168.2.123/photobackup /media/philroche/photobackup

Is anyone else experiencing this and where should I file a bug, or perhaps it is an intentional change? I did ask this on IRC in #ubuntu but no reply.
A similar question was posted @ Nautilus not showing mounted drives in side bar

A: I can only talk about a cifs mount. 
I never noticed that before but it's probably because of how I mount these shares which you may consider as a work around for your situation.
I have a guest share that I want to mount. If I try to mount it your way it does exactly what you said: 
sudo mount.cifs //server/share /home/morbius/Public -o guest

But if I mount it in fstab as a "mount as required" entry it does list it on the side panel of Nautilus. My entry in fstab would look like this:
//server/share /home/morbius/Public cifs guest,user,noauto 0 0

As soon as I save fstab a "Public" folder appears on the side panel of Nautilus. If I click on it ( as an ordinary user because of the "user" option ) the share is mounted . This will work if the mount point is in my home directory or under /media. It will not work if the mount point is anywhere else. Note: these shares will not automount (noauto). They will only mount when I click on the icon on the side panel. They can also be unmounted from that same icon.
I suspect what is happening here is that because of the mount point location and the fact that it is in fstab it induces a udisks response that forces the icon to appear on the side panel. 
Also, for me these are known shares on known hosts so if you use mount.cifs manually to mount random shares on random hosts this workaround will not help much.

A: This has now been resolved as part of glib upstream updates.
