How to upgrade Bitcoin Core from 0.18 to 0.20 on Ubuntu 18.04? I've installed Bitcoin Core on Ubuntu 18.04 (CLI). Now, the version 0.20 of Bitcoin Core is released and I want to upgrade my server to it, but it seems the new version is not included in PPA yet. May you help me to upgrade my Bitcoin Core server to 0.20 in a safe and correct way please?
This is how I usually do it. Check the wget links in https://bitcoincore.org/bin

# Download Bitcoin Core packages for Ubuntu

wget https://bitcoincore.org/bin/bitcoin-core-0.20.0/bitcoin-0.20.0-x86_64-linux-gnu.tar.gz

# check the checksum and fingerprint //optional
wget https://bitcoincore.org/bin/bitcoin-core-0.20.0/SHA256SUMS.asc
wget https://bitcoin.org/laanwj-releases.asc
sha256sum --check SHA256SUMS.asc --ignore-missing
    &gt;expected: xxx.tar.gz: OK
gpg --import ./laanwj-releases.asc
gpg --refresh-keys
gpg --verify SHA256SUMS.asc
    &gt;expected: Good signature from "Wladimir J. van der Laan ..."

# extract, install and check versions of the binaries
tar -xvf bitcoin-0.20.0-x86_64-linux-gnu.tar.gz
sudo install -m 0755 -o root -t /usr/local/bin bitcoin-0.20.0/bin/*
bitcoind --version
    &gt;expected: Bitcoin Core version x0.20.0
