Someone else asked a similar question in April (here: Remmina 1.2 Save Connection), but there were no responses. I didn’t see a way to amplify the question, as opposed to providing an answer. So, I’m asking again and hope I don’t get flamed.
Short story: Can’t create/save a connection with Remmina 1.2.0-rcgit-19
Longer explanation: I run Remnima 1.1.2 on Ubuntu 16.04 Desktop and it works just fine. I have two connections created and saved. To create a new one, one clicks on the icon with “Create a new remote desktop file”.
I created a Vmware Player virutal machine, also Ubuntu 16.04. I opened the Ubuntu Software application and removed Remmina 1.1.2. Remmina 1.2.0 was available via Ubuntu Software and I installed it. I can create a ‘quick connect’ and RDP to a system on my home network. It connects and works fine.
What I can’t do is – create and save connections.
The icon “+” brings up a dialog box and I can fill in all the requested info. However the “Save” button is grayed out.
Per the FAQ, I checked for the location of the profiles (remmina.pref) and came up empty. I finally found the remmina.pref file in “~/snap/remmina/174/.config/remmina”. I copied a remote desktop file to that folder (123456789.remmina [or whatever]) and fired up remmina. Nope, it’s not found/listed. I also did “touch x.x” and it was just fine. I have write access to the folder.
So, I’m puzzled on where/how to create and keep a connection. All I can see to do is quick connect.
