Dear MicroG

The instructions https://lineage.microg.org/ say

Before installing the ZIP you should check that it has the correct signature. You have to use a Python script to verify the signature, available here. Install Python 3 (if not already done) and the required packages (as explained in the README), then run:

python3 update_verifier.py lineageos4microg_pubkey lineage-microG.zip

I have no experience of verifying signatures.

I have no experience of python.

I think I have downloaded and installed Python 3 correctly.

I have downloaded the microG zip.

Could you talk me through the steps to check the signature please ?

In case it’s important - I am using macOS 10.13

Yours sincerely ROMMMELLL

    Dear K

    I changed the directory as you instructed.

    Afterwards, in the CLI, I typed pwd and hit enter.

    In reply it showed the path ending in update_verifier-master

    I typed python3 update_verifier.py lineageos4microg_pubkey /Users/my user name/Downloads/lineage-18.1-20230614-microG-jfltexx.zip and hit enter

    In reply it showed

    Traceback (most recent call last): File “/Users/my user name/Downloads/update_verifier-master/update_verifier.py”, line 6, in <module> from pyasn1.codec.der.decoder import decode as der_decoder ModuleNotFoundError: No module named ‘pyasn1’

    Did I do something wrong ?

      Please read and understand those prompts. Python missing the module pyasn1 (python3-pyasn1). Its mentioned in the readme as a requirement.

      You can install it via pip3 also as described in the readme.

      If you don’t have pip3 installed on your Mac, I think you can get it via brew. I don’t have a Mac myself, so I’m not entirely sure.

        Dear K

        I found I do have pip3. I installed pyasn1 using pip3.

        I tried again, and got an error message. This time I needed rsa. Which I installed using pip3.

        I typed python3 update-verifier.py etc…

        In reply it showed

        verified successfully

        Thankyou very much for taking the time to help me.

        Yours sincerely ROMMMELLL

            Dear K

            I tried to flash the recovery, but it wouldn’t read the file.

            Then I remembered what you taught me about changing the directory.

            I thought, " Could it hurt to cd into Downloads to tell it where the file is ? "

            I ran the CLI command and it flashed the recovery no problem.

            The same with the adb sideload.

            And now I have LOS4MG on my S4.

            Thanks for taking the time to help me.

            Yours sincerely ROMMMELLL

              Great to hear.

              You can always address files via absolute or relative paths.

              Relative:

              cd /Users/rommmelll/Downloads/
adb sideload lineageos-recovery.img

              or absolute:

              adb sideload /Users/rommmelll/Downloads/lineageos-recovery.img

              Maybe you want to learn a little more about paths to understand how to reference files.

              I suggest you read a little further on that topic and play around with the terminal. Find some tutorial videos if that works better for you.
