Attempting to change pool.cert but getting error message: "Cardano-cli : command not found" on air gapped machine

Staking & Delegation Setup a Stake Pool
1

I’m attempting to change my pool fee by following step 18.4 on the CoinCashew guide but am stuck at the following command on the air gapped offline machine:

cardano-cli stake-pool registration-certificate \
    --cold-verification-key-file $HOME/cold-keys/node.vkey \
    --vrf-verification-key-file vrf.vkey \
    --pool-pledge 25000000000 \
    --pool-cost 345000000 \
    --pool-margin 0.00 \
    --pool-reward-account-verification-key-file stake.vkey \
    --pool-owner-stake-verification-key-file stake.vkey \
    --mainnet \
    --pool-relay-port 6000 \
    --pool-relay-ipv4 <MY PUBLIC IP ADDRESS> \
    --metadata-url <MY METATAG> \
    --metadata-hash $(cat poolMetaDataHash.txt) \
    --out-file pool.cert

Output: “cardano-cli: access denied.” I then tried the sudo command to override:

sudo cardano-cli stake-pool registration-certificate \

Output : “Cardano-cli: command not found.”

I then tried again by guiding the file path using this:

sudo /usr/local/bin/cardano-cli stake-pool registration-certificate \

Output: “cardano-cli: command not found”

Then, I tried copying a fresh copy of the cardano-cli and cardano-node from my block producer node to to my air gapped machine’s /usr/local/bin — same effect.

I’ve done this process multiple times without issue before I upgraded to 1.31.0 using this guide: Update Cardano Node to 1.31.0 - for Coincashew users

Any ideas as to why this is happening?

Have you given cardano-cli enough permissions on your cold gap machined? i.e. chown the file?

Hey Jeremy, thanks for your reply.

I must have given those permission to the original cardano-cli when initially setting up the pool & air gapped machine, but perhaps the new (post-1.31.0 update) cardano-cli has not been given the proper permissions? Do you have any suggestions to fix this?

Jeremy,

I figured out what was wrong:

Right clicked my “Cardano-cli” > Properties > permissions > check “allow executing file as a program”

Thanks for pointing me in the right direction!

No worries. For those finding this, given you need to copy cardano-cli onto your cold box via a pendrive, you need to “chown” the executable to allow you to execute it on your cold box.
