Rafael,
I use Insync, a paid-for service that supplies syncing software for my Google Drive or OneDrive accounts in Linux. Thing is that the package is not readily available in KaOS, so I had to build it using the nice directions on the KaOS Packaging page.
Step 1
Run these commands in terminal:
sudo pacman -Syu
sudo pacman -S base-devel
Step 2
Download the package from Arch Linux's AUR to a folder in your home directory. To do that,
Go to the AUR here.
Under "Package Search" on the right type "Insync" and hit Enter.
In the results click on "Insync 3.9.6.XXX" or whatever version is there.
When you see the Package page, click "Download Snapshot" in the "Package Actions" box to download it to your computer.
Step 3
Locate the package where you downloaded it, right-click it and select "Extract Here."
Enter that new directory (called insync"). Right-click a blank space in the folder and select "Open Terminal Here."
Run this command to build the package and install. Enter password when asked:
makepkg -si
The most recent version builds fine without modifications.
You will need to add the following to the Insync entry on the application launcher under "Environment variables" to get it working in Wayland:
QT_QPA_PLATFORM=xcb
This also needs to be added to its autostart entry in KDE Settings.
