Version: mintUpdate from Ubuntu based version

Linux Mint update manager (mintupdate) Ubuntu-based version, it's a great
application. It includes update manager, kernel and repository manager. 3
in 1.
As well as other very practical utilities, such as installing missing
repository keys.
It can do many things, It's wonderful. By now I think Debian should have a
kernel manager.

If a program is already made and works well, why not have it?

I think Debian should have programs to manage kernels, an update manager
and repositories.
I mean an update manager that doesn't depend on Discover or Gnome Software.
And with more options than synaptic.
I have already reached the necessary knowledge to live without it, but
there are many things that I still don't know how to do. And other users
who do not know how to do it.
If Debian includes these packages in its repositories, it would win over a
large number of users.

I know LMDE exist, but, If someone wants to use SID or Testing?
And the nice thing would be to have these programs on all branches of
Debian.

Thanks and regards.

I support this request, as a new user who experience Debian I think lack of a user friendly interface to manage minor update to packages, but also to help transition from a major release of Debian, like do mint-updater or update-manager (from ubuntu) for not technical user.

I think as MVP that only manage update and major update could be enough.
Yes I know there is already UnattendedUpgrades package, but it lacks of user frienldy ui and only do minor update not a major of OS (https://wiki.debian.org/UnattendedUpgrades)
There is also a wiki page in Debian for AutomatedUpgrade, that summarizes the problem explaining how Ubuntu handle it (https://wiki.debian.org/AutomatedUpgrade)

Can we start from a fork of this tools and integrate in Debian?

Thanks
