user4823: 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:


user89190: 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.

user4823: I was having all sorts of problems with this.  Decided to copy everything from an NTFS drive to a Ext4 drive.  All problems gone...
