Error in install instructions

[Barltarman]

Describe the bug
In the installation instructions, in the table for the ProtonVPN Tray dependencies, I get an error trying to install gir1.2-appindicator3. Error states:

E: Unable to locate package gir1.2-appindicator3

** Resolution **
I was able to resolve this error by changing the package name to gir1.2-appindicator3-0.1

Thinking the installation instructions need to be updated?

Which distribution are you using?
Do you need to install the libappindicator dependency?

Sorry I should have said that, Ubuntu 20.04.

Trying to install the Tray functionality.

Hi @Barltarman :)

I tried to recreate this with Ubuntu 18.04 and it worked fine for me, got Note, selecting 'gir1.2-appindicator3-0.1' for regex 'gir1.2-appindicator3'
The following NEW packages will be installed:
gir1.2-appindicator3-0.1

I don't think that the readme should be updated since the package managers are (and should) be able to identify this themselves.

OK I've just had to reinstall 20.04, ran through the instructions and again had to add the "-0.1" to the end of "gir1.2-appindicator3" to get it to install the dependency.

Here is the output of the command:

$ sudo apt install -y gir1.2-appindicator3 libnotify-bin

E: Unable to locate package gir1.2-appindicator3

Just FYI in case anyone on 20.04 has the same issues.

I confirm both the issue and the resolution provided by @Barltarman Thanks, man.
edit: Ubuntu 20.04

Confirmation of duplicate instances of this on Pop OS (Ubuntu based) 20.04, setup two brand new installs, had to use the -0.1 version of gir1. 2 app indicator.
No errors indicating that it needed that version just that it couldn't find the listed one.

Ubuntu 20.4 same issue, solved with:

sudo apt install -y gir1.2-appindicator3-0.1 libnotify-bin
