TryNinja,
Thank you for your post. I have reviewed the link. I have the tarball file located on my Ubuntu 18 desktop. When I select it and right mouse click there is an "Extract File" command which extracts the tarball file content. Am I correct to assume this eliminates the need to use the command shown below?
tar xzf bitcoin-0.18.0-x86_64-linux-gnu.tar.gz
Yes. This command extracts the tar.gz file (notice the folder in the same directory).
Also in the instruction from your link I do you understand the purpose of the "-m 0755" text included in the command shown below?
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-0.18.0/bin/*
Im not super familiar with this command in specific, but AFAIK this sets the permission of the rules to be executed and read.
Lastly, if I remember correctly there is a BIN folder and inside that BIN folder there are six files. Where is the DEB file located? I compare the DEB file to the EXE file used in Windows10 world to install an application. Shouldn't I be using a DEB file to install this application? This is one aspect that has me confused.
This command already installs the software by moving the right files to an accessible folder. There is no .deb file. I even believe that running the bitcoin-qt file in the extracted folder should work.
Lastly, can you share any knowledge you may have regarding dependency files Bitcoin Core needs to install correctly?
Or does Ubuntu 18 already have all dependent files Bitcoin Core needs? Thanks for your help with this matter.
I believe it already has what it needs. In any case, an error will show up, then we can debug it.
