Topic: Install old bitcoincore version on Ubuntu (Read 135 times)

There should be error message on your terminal or debug.log file. But since you attempt to run 32-bit application on 64-bit OS, it's likely the reason is missing 32-bit libraries.

I DO NOT RECOMMEND this option when Bitcoin Core have 64-bit version, but you could try this guide https://askubuntu.com/a/454254.

You're looking for the file command:
One of the most powerful things on Linux is the command line. Even if there's a graphical alternative, I often find myself just typing things because it's faster.
To start learning some of the basics, you could for instance use Bash cheat sheet: Top 25 commands and creating custom commands.

Is not that bad. For me, the 32 bit version does not run, no idea why.
It's stupid that Linux does not make a proper error message.
Therefore, the cause could not be found for so long.
They still helped well, I'm very grateful for that :-)

@DaveF
Maybe you want to edit your post above, with a note that the 64bit version is better? Only for other users who read this later.

That's on me it's the file I recommended. *But* I just did a test and that 32 bit version runs fine on my 64 bit system.
So, yes the one you ran is better suited for 64 bit, but the 32 bit version should run fine on a 64 bit system.
Or at least it runs fine on my system.....

Have found the error.

Only for info, this was the wrong version.
This is apparently only on 32bit.

The right version is:

Now it works as expected.
Thank you for your help and patience with me as Linux layman  :-)

Just to make sure it has the correct permissions. Try to run "chmod +x bitcoin-qt" and then run "./bitcoin-qt" again.

I made a picture of the mistake:

That's weird, does the error you mentioned only show as "command not found", or is there any other output? Maybe you can share the full output within your terminal. Also, on the bin folder try to run "ls"

"bitcoin-qt" is the executable binary. Take Electrum as an example, it's kind of like the standalone executable version of Electrum.

Even without sudo it does not work, same mistake.


Ok, I'll try it differently.
The "bitcoin-qt" file in the bin folder.
What is this for a file? Under Windows you can recognize at the file extension what it is for a file, but under Linux?

If someone could tell me what a file is "bitcoin-qt", maybe I could find out about the search as I can start.

You shouldn't run bitcoin-qt as root, so omit the "sudo".
Why can't your system find the sudo-command?

I open the terminal in the folder "bin".
I'm in: ".../bitcoin-0.18.1/bin$"
Now I give a: "sudo ./bitcoin-qt"
The error appears: command not found

Use a terminal, cd to the directory, and start it with ./bitcoind (or ./bitcoind & to run it in the background).

But since you're talking about a desktop, you may want to run ./bitcoin-qt instead.

That's exactly my problem.
I unpacked this archive on the desktop.
I can navigate to the file "Bitcoind" in the "bin" folder.
I can not start the file "bitcoind" with double-click on Linux. Is not like Windwos.
So how exactly do I start the "Bitcoind" file on Linux?

Normally not in some cases already!
I do not have to take this risk!

That one is 32bit, OP is better off with the 64bit version.

I'd start with bitcoin-0.18.1-x86_64-linux-gnu.tar.gz.

Extract the .tar.gz, then see README.md:

Usually, newer releases include a few bug fixes. You'll still have those bugs.

Usually, your local blockchain copy won't be destroyed when upgrading. If you worry about having to download 400 GB again, making a local backup doesn't hurt.

Lol.

By the time Bitcoin Core doesn't exist on the internet anymore, we have bigger problems.
But if it makes you feel more secure, just keep a local backup of the .tar.gz

bitcoin-0.18.1-x86_64-linux-gnu.tar.gz  <--Is the native 64 bit version
bitcoin-0.18.1-i686-pc-linux-gnu.tar.gz  <-- Is the 32 bit version, may or may not run on a 64 bit system. Read posts #s 13-15 below.


You unzip & untar it and run the bitcoind in the bin folder.


You did not link the installation files you liked to the executable compiled code. If you want to compile it yourself go to:
https://github.com/bitcoin/bitcoin/releases/tag/v0.18.1
and download the source and follow the instructions that are in the /doc/build-unix.md file

After I reinstall my Ubuntu I had to reinstall the bitcoincore in my old version.

On this page you can download older versions:
https://bitcoincore.org/bin/bitcoin-core-0.18.1/
But I do not know how to install these on Ubuntu.

- Which of these downloads on the page is the right one for Ubuntu 18.4.3lts 64bit ?
- How exactly do you install that then after which it was downloaded ?

I would like to install Bitcoin core from an offline source, which I'm sure on my hard drive sure!


Additional information about my motivation and justifications.

I want to install this older version because I can be sure that everything works like about.
My blockchain database must not be destroyed, it is not an option for me to install the latest version of the bitcoincores.
Please do not discuss with me why I do not install the latest version of the bitcoincore, I will not answer!

At the time, the version 0.18.1 was simply installed as the latest version from the Internet.
However, this is no longer possible with this version.


Furthermore, I would also like to know how to save bitconcore as an installation package on its own hard disk. (Only for Linux )
And how to install the core from this source.
It is so that I keep the direct installing from a source, from the internet, for dangerous.
Because:
- not sure is whether this source still exists tomorrow
- not sure if this source was not changed tomorrow
- the version is replaced with newer versions without which I can influence


That's why I ask for help here!
Thanks very much!
