I’ve got a script in Juno ([source](https://github.com/buildwithjuno/juno/blob/main/scripts/cmc.sh)) that downloads and installs the CMC canister locally. While trying to install a clean project from scratch, I discovered my script does not work anymore because the source of the CMC wasm is not accessible anymore. Anyone knows where was the wasm file was moved? * * * This fails: ```auto IC_VERSION=c9b2f9653afc2da47e5bd527c192090b860acbf0 curl -o cmc.wasm.gz "https://download.dfinity.systems/ic/$IC_VERSION/canisters/cycles-minting-canister.wasm.gz" gunzip cmc.wasm.gz ``` Because [https://download.dfinity.systems/ic/c9b2f9653afc2da47e5bd527c192090b860acbf0/canisters/cycles-minting-canister.wasm.gz](https://download.dfinity.systems/ic/c9b2f9653afc2da47e5bd527c192090b860acbf0/canisters/cycles-minting-canister.wasm.gz) returns ```auto AccessDenied Access Denied ... ``` ---

Forgot to close this. I believe wasm hosted by download.dfinity.systems are deleted after 6 months, therefore the “old” wasm I was trying to download was not available anymore. To solve the issue I bumped the commit number to most recent and luckily, there was no breaking changes. So my deploy script for local development was still ok. > > > Signed-off-by: David Dal Busco \ ---

I would like to add that in this form, the `CMC` will not be able to create canisters using the `notify_create_canister` method. I ran into this issue [here](https://forum.dfinity.org/t/canister-does-not-consume-cycles-local/17852/8) and the solution suggested was to deploy a locally modified version of `CMC`. I wrote [a small readme](https://github.com/rabbithole-app/rabbithole/blob/main/src/backend/cmc/README.md) how to build a custom `CMC`, a link to [`cmc.sh`](https://github.com/rabbithole-app/rabbithole/blob/main/scripts/cmc.sh). I hope this helps someone 🙂 ---

In case someone is facing yet another issue trying to deploy the Cmc locally > Error: Failed while trying to deploy canisters. > Caused by: Failed while trying to deploy canisters. > Failed while trying to install all canisters. > Failed to install wasm module to canister ‘cmc’. > Failed during wasm installation call: The replica returned a replica error: Replica Error: reject code CanisterError, reject message Canister rkp4c-7iaaa-aaaaa-aaaca-cai trapped explicitly: Panicked at ‘Deserialization Failed: “Fail to decode argument 0 from table0 to opt record {\n exchange\_rate\_canister : opt variant { Set : principal; Unset };\n last\_purged\_notification : opt nat64;\n governance\_canister\_id : opt principal;\n minting\_account\_id : opt text;\n ledger\_canister\_id : opt principal;\n}”’, rs/rust\_canisters/dfn\_core/src/endpoint.rs:49:41, error code None Try again. For no reason, I just restarted my script and it worked out.
