Stuck at verifying bitcoind operation due to permission problem

[bioterra]

Describe the issue

I started with a clean install, and followed all steps in the Guide. When executing:

$ ls -la /home/bitcoin/.bitcoin/.cookie

I get the response:

ls: cannot access '/home/bitcoin/.bitcoin/.cookie': Permission denied

Location in guide

Bitcoin > Verification of bitcoind operations

Environment

• Hardware platform: Raspberry Pi 4
• Operating system: Debian GNU/Linux 12 (bookworm)

Additional context

Also, the subsequent steps in the guide lead errors:

tail -f /home/bitcoin/.bitcoin/debug.log

Returns:

tail: cannot open '/home/bitcoin/.bitcoin/debug.log' for reading: Permission denied

And,

bitcoin-cli getblockchaininfo

Returns:

error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set. See -rpcpassword and -stdinrpcpass. Configuration file: (/home/admin/.bitcoin/bitcoin.conf)

Probably all related. I triple-checked whether I executed all previous steps in the guide and that seems to be the case... What to do?

User from which you are running these commands must belong to the bitcoin group.

Thanks, I am running this from the "admin" user, as per the guide, and I added "admin" to the bitcoin group via:

sudo adduser admin bitcoin

Also as per the guide.

(If I re-run the above command it says: "adduser: The user admin is already a member of bitcoin.")

[bioterra]

I found a solution, I had to give read+execute rights to members of the bitcoin group on the folder /home/bitcoin/

sudo chmod g+rx /home/bitcoin/

After that, the command ran as expected from the user admin:

admin@raspibolt:~ $ ls -la /home/bitcoin/.bitcoin/.cookie
-rw-r----- 1 bitcoin bitcoin 75 Mar 17 20:36 /home/bitcoin/.bitcoin/.cookie

I do think this chmod command is not part of the guide/walkthrough, should it be added?
