Yes it's the first app to update indeed 😉

Same issue, can't install Touch.
Data and System already formatted to ext4
UBports recovery flashed
Installer is always stuck on "ADB is scanning for devices".
Any alternative ways to install and/or ways to get it recognized through adb?
On Win7

@keneda yeah, exactly i thougt about touch keys under cover of the phone. I understand that ubuntu touch works on gestures but i think that this would be grate idea to create some shortcuts to some applications/functions. A lot of phones have additional keys on cover for example mi 9 (to google services).

@siucdude Hi, that seems to be a issue on some devices. I have made a bug report here: https://github.com/ubports/ubuntu-touch/issues/1695

@raphaey As I said above I don't have this device so no direct knowledge but, from what you say you only had recovery installed. Either try again and choose the wipe option on the installer you should not have to do anything other than follow the installer instructions.
Or as @Dimka said
"managed to establish Ubuntu Touch . first put TWRP , cleared everything . and only after cleaning installed Ubuntu Touch . Thank you all for the answers, I hope I have one problem with the installation"
Use twrp wipe everything then try the installer. The newest device I have is a OP3 so am not the ideal person to help on this. Though that had a similar issue with needing twrp to wipe, clear and format cache and data for the installer to work
