error: failed to select a version for the requirement `aes = "^0.2"`

[satindergrewal]

Hi,

I'm trying to compile zec paper wallet from code but it's keep giving me error for aes dependency. I checked on https://crates.io/crates/aes/versions which shows the specific version of aes which is used at git hash of librustzcash dependency got deleted about 3 years ago.

I'm not a rust native programmer. Can you please help fix this issue? Would very much appreciate your help on it.

Thanks Satinder

I ran into the same error. For now the only thing i can add is that i was able to make it work by downloading the binaries https://zecwallet.co/paper.html#download for linux.
