Unable to start bitcoind ORIGINAL QUESTION:

Anyone know why I am getting the following error message?





Other possible relevant info:

Config file location

/home/.bitcoin/bitcoin.conf




Config file content:

server=1
testnet=0
txindex=1
rpcuser=[username redacted]
rpcpassword=[password redacted]




bitcoind location:

/home/bitcoin-0.19.1/bin/bitcoind




OS:

Ubuntu 18.04 (fully uptodate)



bitcoin-core download location:

sudo wget https://bitcoincore.org/bin/bitcoin-core-0.19.1/bitcoin-0.19.1-x86_64-linux-gnu.tar.gz




login username:

bitcoin




folder/file permissions (recursive) for bitcoind and bitcoin.conf:

777




After a few seconds, bitcoind automatically stops without warning and allows me to start it again, only to automatically stop again.  How do I figure out why it is not starting, or why it stops after a second or 2?  When it stops, it does not show any error messages in the terminal.  I only know something is wrong if I run a bitcoin-cli command, as seen in the screenshot above.



UPDATE ONE:

./bitcoind output below:
It's possible your blockchain is corrupted or you have multiple bitcoind processes running. Kill the bitcoind process, go to /home/bitcoin/.bitcoin and delete the blocks, chainstate and database directories using 

rm -r blocks
rm -r chainstate
rm -r database


then start the daemon again without the '-daemon' flag to see if it progresses further.
