I am building an altcoin contract using zeppelin library to make it upgradeable using a proxy. I also use a Ownable cotract that allows me to pass ownership to another address in 2 phases. Transfer Ownership with the address as param and Claim Ownership which must be called with the previously address. I am using Ganache app on ubuntu, having 10 unlocked accounts. The issue lays in this code:

Coin.deployed().then(coin => {
    TokenProxy.deployed().then(function(proxy) {
      coin.transferOwnership(proxy.address, {from:owner}).then(function(res) {
            proxy.claimOwnership({from: proxy.address}).then(function (res) {
              console.log("Done!");
            }).catch(function (e) {console.log(e);});
          }).catch(function (e) {console.log(e);});
        })
      })

The problem is that the proxy address will not be one of those 10 in the list so I end up with

Error: sender account not recognized

Basically I am not sure if it's part of the ganache node (but if it is, for sure it is locked).

I tried to unlock it using web3 and a couple off different things. Nothing helped.

I think the error lays on the fact that you are using an smartcontract address instead of a valid ethereum wallet account.

Unlocking a contract account is not possible not only on Ganache but on the rest of the networks as well. You cannot send a transaction with the contracts address as the from address since you do not have the private key for that address. If you could just unlock the contract's address what is there to stop someone from unlocking your address.

If you wish to call a function from a contract's address you have to call the function you wish to call from within the contract itself.
