Failed to start bitcoin daemon using Ubuntu 20.04

Question

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 Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; vendor pres> Active: failed (Result: exit-code) since Wed 2020-12-30 15:12:05 UTC; 23s > Process: 2411 ExecStartPre=/bin/chgrp admin /etc/bitcoin (code=exited, stat>

Here is how my bitcoind.service looks. I changed the user and group from bitcoin to admin. [Unit] Description=Bitcoin daemon After=network.target

[Service] ExecStart=/usr/bin/bitcoind -daemon
-pid=/run/bitcoind/bitcoind.pid
-conf=/etc/bitcoin/bitcoin.conf
-datadir=/var/lib/bitcoind

Make sure the config directory is readable by the service user

PermissionsStartOnly=true ExecStartPre=/bin/chgrp admin /etc/bitcoin

Hardening measures

####################

Provide a private /tmp and /var/tmp.

PrivateTmp=true

Deny access to /home, /root and /run/user

ProtectHome=true

Mount /usr, /boot/ and /etc read-only for the process.

ProtectSystem=full

Disallow the process and all of its children to gain

new privileges through execve().

NoNewPrivileges=true

Use a new /dev namespace only populated with API pseudo devices

such as /dev/null, /dev/zero and /dev/random.

PrivateDevices=true

Deny the creation of writable and executable memory mappings.

MemoryDenyWriteExecute=true

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 server=1

zmqpubrawblock=tcp://127.0.0.1:28332
zmqpubrawtx=tcp://127.0.0.1:28333

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

Utimately I got ubuntu systemd[1]: Failed to start Bitcoin daemon.

if you installed Bitcoin core using a PPA, it means your script is looking for bitcoind in the wrong place.

To confirm where your bitcoind was installed, use whereis bitcoind

This will likely return /usr/local/bin/bitcoind, now your script is looking for it in /usr/bin/bitcoind so you can either copy it into that directory

sudo cp /usr/local/bin/bitcoind /usr/bin/bitcoind

or change your script to look for it in /usr/local/bin/bitcoind
