Management_canister - install_code - out of cycles

Developers Getting Started

I am studying management_canister.

let foobar = install_code(install_code_arg).await.unwrap();

I get an error with install_code. I am running locally, not on mainnet. I would like to get rid of the error.

Installing code into a canister requires cycles. Apparently you created your canister with 0 cycles. If I’d guess how it happened: You did dfx canister create --with-cycles <0.1 Trillion>. Creation of the canister costs 0.1T, which leaves 0 cycles for the canister itself.

Local remediation: dfx ledger fabricate-cycles <cycles> <canister>
Mainnet: dfx canister deposit-cycles <cycles> <canister>
