        @marc_aurel you need to run fastboot erase cache before starting the installation.

        See https://github.com/ubports/ubports-installer/issues/6

          Thanks for your help. The last suggestion did help to run the installation script without the storage space error. UBports installer shows a successful installation:

          Unfortunately the device remains stuck in recovery mode. I could validate this with adb get-state.

          If I reboot with adb reboot, the old system 14.10 is booting. Some ideas?

            @marc_aurel if you get stuck in the recovery screen more time than the "normal", you can unplug and plug the phone (it seems that sometimes adb and fastboot keep fighting for the usb port control)

              @advocatux Thanks for your response. I tried the installation again:

              The UBport installer shows the „success“ message, but the device keeps in the recovery mode. I can access the device with adb.

              I seems, that the files are copied to the device, but the installation process hasn’t started.

                @marc_aurel how long is it stuck in the recovery screen? If it's too long, say more than 3 or 4 minutes, you can try to reboot the phone pressing and holding the power button until it reboots.

                I used that method successfully with my Nexus 5 a couple of times already 🙂

                  I have waited for half an hour, then I tried to reboot. The device doesn’T respond to the power button. I have to use adb reboot. But then the old system starts.

                    Some more suggestions? The UBports Installer completes with a success message, but the new UBports version isn’t installed. Is there a different approach for installation, maybe with fastboot within terminal?

                      Finally I could manage to update the phone.

                      The update failed with macOS Mojave and my Windows 10 VM. Both systems seem to have driver problem although I'm able to flash phones with macOS Terminal commands. The update with my Linux VM failed either as I reported. Howsoever after I managed to clean the cache in the recovery mode on my phone, the process with Linux was successful. A assume, there is also driver or USB controller issue with MacBook Pro.

                      Thanks for your support. Sometimes one need to try it again and again and aigain.

                        @marc_aurel you're welcome. The usual issue with MacOS & the installer is that the necessary tools (adb & fastboot) are not in the user's $PATH and the user needs to fix that 🙂

                          @advocatux Thanks. I’ve installed the full Android SDK on my MacBook for App development. Is this a conflict?

                            @marc_aurel maybe the whole Android SDK is a little bit over the top but it shouldn't be a problem.
