bitcoind – Failed to start bitcoin daemon using Ubuntu 20.04

Hey I keep getting this error everytime I run sudo systemctl enable –now bitcoind

Job for bitcoind.service failed because the control process exited with error code.
See “systemctl status bitcoind.service” and “journalctl -xe” for details.

When I input sudo journalctl -xe –unit bitcoind I get this.
bitcoind.service – Bitcoin daemon

Here is how my bitcoind.service looks. I changed the user and group from bitcoin to admin.

Here are the steps I made before:
~$ cd src
~/src$ git clone –depth 1 –branch v0.20.1 https://github.com/bitcoin/bitcoin.git
~/src$ cd bitcoin
~/src/bitcoin$ ./contrib/install_db4.sh pwd
~/src/bitcoin$ ./autogen.sh
~/src/bitcoin$ export BDB_PREFIX=’/home/ubuntu/src/bitcoin/db4′
~/src/bitcoin$ ./configure BDB_LIBS=”-L${BDB_PREFIX}/lib -ldb_cxx-4.8″ BDB_CFLAGS=”-I${BDB_PREFIX}/include”
~/src/bitcoin$ make
~/src/bitcoin$ sudo make install
~/src/bitcoin$ bitcoind -version
vi bitcoin.conf

~$ sudo mkdir -p /etc/bitcoin
~$ sudo cp bitcoin.conf /etc/bitcoin
~$ sudo chmod 644 /etc/bitcoin/bitcoin.conf
