@karel I don't know the name of the email notification app from 16.04. But I used it all the time. Did it carry over to 18.04? If not, is there a replacement, or a way to have email notifications in the Top Bar? Thanks.

@L.D.James Mailnag Mail indicator (GMail, IMAP, POP) for GNOME 3. To install it in Ubuntu 18.04 open Ubuntu Software and search for Mailnag. This is a GNOME Shell Extension that is a replacement, not an app that was carried over from 16.04.

Thanks for the definition of Gnome Shell Extension vs App.

Mailnag puts a little notification icon in the notification area of the GNOME Shell Panel, next to the indicator icons for networking, language, volume, etc.

The search in Ubuntu Software is still so clumsy in Ubuntu 18.04 that it's hard to find packages in Ubuntu Software. To compensate for this, Synaptic package manager can now be opened read-only without typing the user password first in 18.04.

Thanks. The Show Applications button worked in finding it. I used the apt manager to install it.

My biggest problem what that I didn't know the name to search for. Been trying to find something for this since the night of 18.04 release... I thought it was just a matter of catchup times for little tools like that to come to 18.04.

I ran it from the All Applications menu. It came up with the configuration option, of which I added an imap account. I sent a test message to myself, but am not seeing the notification icon. I recently installed the gnome-shell-extensions.

It's easy to find Gnome Shell Extensions in Ubuntu 18.04 by using the search for Gnome Shell Extensions trick in this answer: askubuntu.com/questions/75530/…

Thanks for the link to the question. I'll study it. Currently having trouble making it appear on the Top Bar, even though it's installed, configured, and turned on.

There's a command that refreshes all the indicator icons in the Gnome Panel without rebooting or login/logout - it's setsid gnome-shell --replace Credit goes to hannesvr: askubuntu.com/questions/484989/panel-icons-disappear-at-startup/…

Thanks, will give it a try. I have 47 windows that I'd have to reload if I reboot or login/logout.

Of course all your open windows stay open with setsid gnome-shell --replace

I'm familiar with the "--replace" command which I used so often with Unity. I have executed the command. It blanked and refreshed the screen, but still no mailnag icon.

There might be problems with the way my gnome-shell-extensions is installed. It doesn't show the type of screen that I believe should be shown... give me a second and I'll post a screen capture of what it.

I don't know how to get to a screen that looks like this:

On the "Appearance" screen (from Gnome-Tweaks) it shows an Exclastion mark and the drop-down under "Shell" is disabled.

Open Ubuntu Software app. On the first page when you open Ubuntu Software click All and then click the Add-ons button. Scroll to the top of the Add-ons screen and then you will see a light yellow bar with an Extensions Settings button on it. Click the Extensions Settings button. This will show a window with all your installed Gnome Shell Extensions. Beside each installed Gnome Shell Extensions is an ON/OFF slider to enable/disable it.

The Shell Extensions window looks like this:

Ok...Thanks!

I feel kind of dumb, I'm at the last step in your description, but I'm not seeing a method to activate the mailnag extension. If might be in a group that I should activate for that type, but I can't identify what to click. I guess I could start off from the top and start turning them on, one by one, until I get the right one... am I missing something obvious?

I hope I'm not taking up too much of your time... I'm sure I can eventually figure it out, now that I'm on the right track.

Run sudo apt install gnome-shell-mailnag to install GNOME Shell integration for Mailnag. Run mailnag-config to configure it. This window will pop up:

In the Accounts tab of the above screenshot you need to click the + button to add a new account and add each one of your email accounts individually.

Thanks... I had done everything else. The missing step was, "apt install gnome-shell-mailnag". I had installed "mailnag", but not "gnome-shell-mailnag". Any issue I have ever had has always been something extremely simple.

Sometimes it takes me (as in this case, weeks) or longer, to realize the missing step.

Thanks a lot... this is now an extreme convenience.

A gnome is a dwarfish earth dweller so it's obvious that everything has to work in Gnome if you work hard enough for it. Not so obvious to me because for some reason things usually always work quickly with me. So I had to look up the definition of Gnome to see if there is any reason for the roundabout way that Gnome has of doing things compared to Unity.

Have you read the new Meta posts recently? It's downright sinister the way people are posting answers to tag questions switching the word Dash with the word Dock. Calling the Gnome Panel a top bar or a menu bar. Calling the Dock a side panel. Gnomes are also supposed to have a sinister influence. It will make more sense to you when you read the new Meta posts about tags and tag synonyms.

I'm not a sinister person. Unlike many geeks I don't like heavy metal music, so I bought the opera Orfeo ed Euridice composed by Christoph Gluck instead, and also watched the DVD of it twice. Being Orpheus is OK for me I guess.

Thanks for the tips. I try to use the wordings that I find in the app or in the manuals or instructions for using the environment. That's where I get the "Show Applications" button name, and the "Top Bar" name when describing an issue.

I realize the names will change based on the environment, such as the "Super Key" for Ubuntu, the "Windows key" for windows, and I forget what the Mac calls their button that does the same thing. But if I were going to describe something, I'd look it up to try to get right.

I'm going to reboot my computer as soon as I can catchup with some of the activities on running. It's probably not related, but it's not catching the new emails. It might have to do with Thunderbird reading the list first and removing the new mail flag.

It often takes me a while to get things worked out right. I'm used to it.

It should be working soon... I found another simple thing that I was missing. I can't believe I had typed in my email address for my username. It should be working soon.
