This is an older version and may not contain the required secp256k1_ecdsa_recover symbols. In order to get the latest version that supports the required symbols, I need to update to a newer library version. Maybe 20.04 does not support running this project at all

The problem is not that you have a too old sekp236k1 library installed but that you have installed this library and it has the same name as some library that we ship with warthog and the system library has higher precedence. We will rename the shipped library in our repo such that it does not have the same name anymore.
For how you can remove the os package that installed this library. Our you prepend to every warthog command this: LD_LIBRARY_PATH=/home/meirong/youzhu/new/build/src/wallet/./../../thirdparty/secp256k1

Wallet file 'wallet.json' does not exist yet. Create a new wallet file using the '-c' flag.

It works now. Congratulations. You need to create a wallet file by appending the "-c" flag.
