need some help for electrum 4.1.5 in raspberry pi 2b

[holahapi]

I am using raspberry pi 2b with raspberry pi os.

When execute the Linux "Appimage", it create a file with garbled name in the same folder, and nothing happen.
Q1: Is the appimage not working in raspberry pi 2b (A 900MHz quad-core ARM Cortex-A7 CPU)?

When using method "Installation from Python sources"
at the step verify command,

Code:

gpg --verify Electrum-4.1.5.tar.gz.ThomasV.asc Electrum-4.1.5.tar.gz

it return "Can't check signature: No public key"
Q2: Is this mean verification not success? and I need a public key?

When I run the electrum, It return the following warning, but the electrum opens and able to create wallets.

Code:

python3 Electrum-4.1.5/run_electrum

Check this if you've missed the first step: https://electrum.readthedocs.io/en/latest/gpg-check.html
I think the download page only shows the command for users who already have ThomasV's public key.

Yes and yes.
When verifying GPG signatures you need 3 things:
1. The file that was signed
2. The signature of that file
3. Public key of the person who produced the signature

You are missing #3 here.

q3 the warnings don't seem to impact electrum's operation so i would ignore them.
