Ask HN: Is there any SysAdmin Linux GUIs?

I was wondering, is there's any SysAdmin administration tools that let run/configure/administer a linux server(possibly Ubuntu) with a GUI?

It can be anything from a webserver serving the admin web dashboard or a more traditional desktop GUI.

In terms of features I would expect being able to:

- manage systemd services

- manage mounted disks

- managing the filesystem(and all the users/permissions/groups concerns), especially with ACL in mind

- update/upgrade/package-management(install/remove)

- SSH console in case it's not running on the server locally

- (optional) handling encrypted partitions(boot/root/external)

I'm even willing to pay for it, given a price for a solo SysAdmin and it's middle/low tier servers.

ps: I know that many would suggest to learn the terminal way and be content with it and I already do like this so far, but I just want to ease my life from this point of view.
