Was/is there some temporary de-federation with other instances because of this? I've commented on a feddit.de post like 9 hours ago, and its still not visible over there.
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.
cd means change directory. Its a CLI (Terminal) tool to - as the names suggests - change the directory you want to work in. It our case the folder with the unzipped files.
Assuming your Mac username is "rommmelll" and that zip file is in your downloads folder, the path should be something like "/Users/rommmelll/Downloads/update_verifier-master". So the command cd /Users/rommmelll/Downloads/update_verifier-master should work.
Hint: you can use the tab key to auto-complete here. Type cd /Users/r and press tab and it should fill in to cd /Users/rommmelll. Terminal app will try to autocomplete everything after the last /, in this case r. If there is more than one option with r it will list them and you can specify it more with rom and press tab again. See this video for example, for a few more details.
Once you've cd'd into that folder you can continue with the python3 command from above.
Note: If you don't specify a full path, something like /Users/rommmelll/some/file.zip, the Terminal app will always expect the files you're referencing in the current directory. So either use cd as mentions above, or use full qualified paths. Use pwd (print working directory) to find out which path you're currently in.
Also have a look at some tutorials regarding the Mac Terminal.
As already mentioned in your former post, this is just to verify the integrity of the files. It's not a neccessary step, but could safe you from a bricked phone.
I think I have downloaded and installed Python 3 correctly.
To find out just open the App Terminal and type python3 and hit return. Your should see something like this
Python 3.11.3 (main, Apr 5 2023, 15:52:25) [GCC 12.2.1 20230201] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
Download the python script from the mentioned location: Green "<> Code" button > Download Zip. Unzip that stuff.
Open the Terminal again and cd into that folder. Then type
python3 update_verifier.py lineageos4microg_pubkey /path/on/your/machine/lineage-18.1-20230614-microG-jfltexx.zip

I see. Thanks for the info.
