Trying to download KDE Connect in Ubuntu Software

The only unsuccessful part.
I was waiting for it to download but it wasn't moving. So I hit "Cancel" in hope to retry the download. However it shown as installed even though it wasn't. Trying to remove KDE connect resulted in following error: Direct image link
I tried to find a way to delete cache or config for Ubuntu Software (snap-store), but I only managed to delete all icons from it by deleting ~/snap...

Installing via apt

As expected, the good old sudo apt install kdeconnect did its job perfectly.

Pairing KDE connect

As expected, this did not work right away as by default the network adapter is attached to NAT in VirtualBox. As such I couldn't see any devices in KDE connect.

The solution was to change it to Bridged Adapter and select the desired network card. This way it would directly communicate with outside world using my laptop's network adapter.
The setting is located in: (Your VM) > Settings > Network

A new problem arose. Trying to pair my phone with VM instead sent pairing request to host as I have KDE Connect installed on it ~~and both Host and Guest are using same IP address.~~
That problem solved itself after pairing my phone with host computer.
~~KDE Connect dynamically assigns ports in range 1714-1764. I guess at first they were trying to both use the same port, thus host received the pairing request instead, but after pairing and connecting with host, guest had to use different port and now they were able to successfully connect.~~
Edit: Nope, they do get separate IPs. I don't know why this occurred then.

So I was able to connect both my phone and laptop:

TeamViewer

After downloading the TeamViewer .deb file I just double clicked it and then clicked on install in the installer window

Then I just normally launched TeamViewer from app menu and requested connection from my phone.
Ubuntu just asked to select display and allow remote interaction

And this is a screenshot from my phone:

I'll try to download Ubuntu 23.04 ISO overnight and try it tomorrow on VirtualBox (7.0).
