Network manager applet shows ‘not connected’, and one unmanaged Wired connection, internet working

I have no experience configuring network manager by text configs, used only GUI. When moving mouse over NM tray icon there are tooltip “Not connected”, however I see one connection then clicking it – “Wired unmanaged”. Internet working fine.
I make new ethernet connection with priority 10 but it not appear in NM applet menu. plugin menu enter image description here

I have change NM config, as suggested in other questions:

[ifupdown] managed=true 

Question is: how to connect by new created ethernet connection, or at least make “wired” connection managed?

Download Workflow Manager Components Without Web Installer

I have spent hours trying to pull together the Workflow Manager installation components for SharePoint 2013 in an environment that doesn’t have Internet access. Microsoft in their infinite wisdom seem to think that the web installer is available to every environment.

Where can I download all the Workflow Manager components for offline installation without using the Web installer?

Populate Snapshot manager with missing snapshots or revert to one manually?

Is there a way to populate the Snapshot Manager with snapshots that are listed in the datastore but not under Manage Snapshots. Is there a way to either populate Manage Snapshots or using something like vmkfstools revert to the snapshot manually?

Long story short, I had a hardware failure and had to re-add the datastore to the Linux VM. I believe before the failure that I was using Portal-000003.vmdk but when I try to start the system with that datastore I get the following error: Failed to power on virtual machine Portal. File system specific implementation of LookupAndOpen[file] failed

When I try to using Portal.vmdk it boots up fine, but seems to be running code from 2015. When I look at the Datastore I have several vmdk files:

Any suggestions on what else I can do to revert back to the latest good snapshot?

Thanks.

Finder-like File manager that displays thumbnails arbitrarily large and allows free movement

I’m looking for a file manager that will make it easier to match up photos. I have two sets of photos with different names, and I need to rename like photos with similar names. I have been using PCManFM, but it has two problems:

  1. I can’t make the thumbnails any large. I need something like OS X where I can set the dimensions of the thumbnails, for instance to 128×128 or 256×256 as my needs change.

  2. I need to be able to drag files around and sit them arbitrarily on the desktop. To do this I need to disable any automatic sorting or positioning of icons (also similar to what OS X provides). In this way I can drag similar files next to each other before they get renamed.

PCManFM does not provide either functionality. I have tried Thunar but while it lets me “zoom in” increasing the thumbnail size it isn’t always enough. In addition, it doesn’t let me disable the automatic sorting and resizing.

I have seen Pantheon but I’m running LUbuntu and don’t want to mess with trying to install it unless I know it will work.

Are there any other file managers that will do this which will easily run on LUbuntu 18.04?

Q: Document Library File Permissions – Manager vs Members

I’ve been asked to make a library / repository of resumes from team members. So basically, permissions should be as follows:

Members – Can upload resume and edit their submissions but not view other files in the same folder.

Managers – Can view and download all items in the folder.

Can anyone help how to accomplish this? I’m new to SharePoint development and it would really be a great help. If anyone can send me links to similar topics, that would be great as well. Thank you.
