No, unfortunately not yet.
I have tried the Webinstaller again.
https://grapheneos.org/install/web#enabling-oem-unlocking
When I go to systems Settings, the OEM unlock is grey and it says Bootloadder is already unlocked.
I am assuming that this is ok.
Maybe flashing as non root is the problem,

When I type "android-sdk-platform-tools-common" into the terminal, I get the following response:
android-sdk-platform-tools-common: Command not found.
However, if I go to the Ubuntu Software Center, I can see that Android SDK Manager is already installed. It is Version 1.2.1.2 A few weeks ago I also installed LineageOS on a older Phone. Therefore I guess that it works.
I have skiped this one: https://grapheneos.org/install/web#working-around-fwupd-bug-on-linux-distributions
since my fwupd version is 1.9.13
Booting into bootloader worked

As long as the telephone is working normal, a Telephone Symbol is at my Ubuntu Task, after booting into bootloader the telephone symbol disapears.
last time i was using the original google cable, now I am using another one which is twice as thick as the original one.
The Pixel6a now says in red "Fastboot Mode" and also in red "unlocked"
I am not 100% sure what to do here: https://grapheneos.org/install/web#connecting-device
I dont know how I can check if my udev ruless are ok?
and now the trouble beginns:
https://grapheneos.org/install/web#unlocking-the-bootloader
this time again the website says:
Error: Failed to execute 'open' on 'USBDevice': Access denied.
therefore I have unpluged the phone and pluged it again
nothing changed
I have reloaded the website,
nothing changed
I have changed the cable to the original google cable
nothing changed
