Use a Python Script to Verify the Signature

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

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.

  You're welcome. Hope you learned a little.
  
  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.

  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.
  
  Thanks K
