Joomla missing component - installation

I have an installation (3.4.8) who it's missing com_joomlaupdate component. It has removed. It has upgraded from a previous 2.x version.
Can I reinstall manually? Or how can I fix situation?

The install package for the Joomla Update Component can be downloaded and installed as you would with any extension.
Joomla Update can be downloaded from:
https://github.com/joomla/joomla-cms/releases/download/3.6.1/com_joomlaupdate-3.6.1.zip

Xamarin.Forms.Maps not showing under installed packages

I am following tutorial https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/map/setup
I created a Xamarin.Forms project
I can browse and search for Xamarin.Forms.Maps I clicked Install
but I don't see it under installed packages
I see that it has a bunch of dependencies, but they dont seem to install automatically.
Do I need to install all of those one by one?
Is there a way to automatically install all necessary dependencies with correct version like in python?
Thanks,

Unable to update the xamarin.support.v4 packages

while updating my NuGet packages I am getting this issue
Unable to resolve dependencies. 'Xamarin.Android.Support.v4 25.4.0-rc1' is not compatible with 'Xamarin.Forms 2.3.5.253-pre5 constraint: Xamarin.Android.Support.v4 (= 23.3.0)'.
Can any one guide me for this issue
Thank You
You should not update Support libraries by your self. Instead update only Xamarin.Forms package and it updates his dependencies automatically.
Now, try to uninstall all Support libraries and Xamarin.Forms, install Xamarin.Forms again and it would add all dependencies needed.
As a reference, take a look at this.
I ran into similar the other week (blindly clicked update and it all went wrong), my solution was to downgrade Xamarin Android Support (I'm on 23.3.0) although I'm only using Xamarin Forms 2.3.4.247 I believe the issues is common.
From memory this was a bit of a pain and had to actually remove them one by one and add them back in (maybe take a screenshot of what packages are installed so you don't forget!), but 23.3.0 was the magic support version.
HTH
Solution 1.
Update xamarin forms to latest version.
Xamarin.Android.Support.v4 25.4.0-rc1 is having some dependence on latest xamarin.forms
Solution 2.
Install older version of Xamarin.Android.Support.v4 .
Check the version dependence before installing and ensure that older version do not have dependence on xamarin forms.

Can't upgrade Xamarin.Forms NuGet package for Android project

When I am trying to upgrade Xamarin.Forms NuGet package from 2.0-2.1 to 2.3.1.114 (latest stable at the moment) I get the following error (even with new blank projects) is there a way to fix it?
Severity Code Description Project File Line Suppression State
Error Could not install package 'Xamarin.Android.Support.v4 23.3.0'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v6.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

Try this option for your project:
This error is most probably because your xamarin forms version is not compatible with Xamarin.Android.Support.v4 23.3.0 available through NuGet. Check this thread on xamarin official forum. As per this thread, 23.3 is not supported by Xamarin forms. On more possible reason is that your xamarin form version is not compatible with the latest update. You can try updating forms to latest version. In case if that doesn't work, then probably you should continue with the version you already have.

Difficulty in uninstalling older phonegap versions

How do i uninstall an already existing version of phonegap(1.3,1.8) because i want to install the new 2.0 and it does'nt get installed without uninstalling older versions. The folder structure of my older version 1.8 does'nt have uninstall option.
Any suggestions are welcome.Thanks.
Cordova 2.0 onwards doesn't really have an 'installer' so you should be perfectly fine to leave your 1.3 if you like.
They only recommend uninstalling old versions if you are not going to use it so that the project template is removed from XCode. If you don't care about that you can leave the old version.
Just follow the upgrade steps from http://docs.phonegap.com/en/2.1.0/guide_upgrading_index.md.html#Upgrading%20Guides to start using 2.1 (which is now out and you should use)
