It's only slow when you open since it needs to extract some files/binary. But it's size shouldn't be changed at all since Electrum (AppImage version) still store it's data on ~/.electrum.

AppImages are for novices. I said what I said.

They are convenient in some situations, and give simplified options for people who aren't technically capable, which is fine, but I tend to find them limiting. I suppose it's not a huge deal for Electrum since most of the things you can do with CLI commands can be done in the console.

FWIW, Electrum already exist on Debian repository for many years though. See https://packages.debian.org/bookworm/python3-electrum.

I wouldn't use the Debian repository for Electrum, and we should discourage newbies from doing so also. The repository is always several versions behind, which could (and has in the past) pose security risks.

The Electrum BTC wallet is also available in the Ubuntu App Centre although it is over 8 years out of date (version 2.6.4). The Debian repository is better but still a little over 2 years out of date (version 4.3.4). When working with financial software like BTC wallets, I prefer the most up-to-date stable version.

Good job. I much prefer the python install. AppImages are clumsy and slow in my opinion. They're also unnecessarily large since they package all their own dependencies, but most of the dependencies are already included in the OS. AppImages also don't give you daemon or CLI options, which I find handy from time to time. I do use AppImages when temporarily booting from a live USB for air-gapped use, but other than that I tend to avoid them.

Maybe I'm just old fashion (in my 70s) but I also prefer a python install over appimages.

Here's a guide I put together a couple of years ago, but I've been keeping updated to some extent. The version is currently set to 4.5.5, so you'll want to make sure to change the commands to point to version 4.5.8 before executing them.

https://bitcointalk.org/index.php?topic=5456909.msg62430610#msg62430610

Thank you @DireWolfM14. Your instructions worked like a charm. I just amended 4.5.5 (wherever occurring) and replaced it with the current version 4.5.8.

I am having a lot of trouble trying to install Electrum on my PC using Ubuntu 24.02. What I want to do is install Electrum on Ubuntu 24.02 so that there is an icon on the screen's Dash that I can click on and directly open the Electum wallet program. Following the instructions at https://electrum.org/#download for Installation from Python sources, I have;

installed the dependencies

Code:

sudo apt-get install python3-pyqt5 libsecp256k1-dev python3-cryptography

,

downloaded package to my Home directory

Code:

wget https://download.electrum.org/4.5.8/Electrum-4.5.8.tar.gz

and

verified signatures

Code:

wget https://download.electrum.org/4.5.8/Electrum-4.5.8.tar.gz.asc

Code:

gpg --verify Electrum-4.5.8.tar.gz.asc

.

Next I tried to install the package using

Code:

sudo apt-get install python3-setuptools python3-pip

Code:

python3 -m pip install --user Electrum-4.5.8.tar.gz

and got the following returned;

Quote

error: externally-managed-environment

× This environment is externally managed

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

After extracting the files from the Electrum-4.5.8.tar.gz folder, I can run this electrum wallet by opening the Electrum-4.5.8 folder, right-clicking on the run_electrum file and selecting "Run as a Program" but first a terminal window opens telling me that "QSocketNotifier: Can only be used with threads started with QThread". I just ignore this and continue using my Electum wallet without difficulty.

Where have I gone wrong and how can I achieve my aim of installing the Electrum wallet with a working icon in the screen's Dash? Any help/guidance would be most appreciated.

I tried running the electrum.desktop from terminal. First I right-clicked on Electrum in my Start Menu and picked Properties. In the File Properties I set "Execute terminal emulator", "Keep terminal window open after execution" and selected OK. Back in Start Menu I clicked on Electrum. The terminal window opened, text appeared and then the terminal window immediately closed (no time to read).

I then opened terminal and cd to ~/.local/share/applications where File Properties says my target file electrum.desktop is. I then tried the following:

I now want to install an app launch in my start menu. I did this by

Code:

cd ~/Electrum-3.3.5
sudo desktop-file-install electrum.desktop

This installed the app launcher in my menu://applications/Internet directory (although it was a hidden app so I had to unhide it).

For this app launcher the target file is "/home/richard/.local/share/applications/electrum.desktop" and the command is "electrum %u"

The only problem is that when I try to launch Electrum in my start menu nothing happens. Where have I gone wrong?

Yes, it was just an access problem. Using

Code:

sudo python3 ~/Electrum-3.3.5/run_electrum

it works.

I have also

Code:

sudo chmod 770 /home/richard/.electrum/daemon

This does not appear to change anything. I still need

Code:

sudo python3 ~/Electrum-3.3.5/run_electrum

After recently installing Lubuntu 18.04.3 LTS on my 32-bit computer, I have been trying to install Electrum 3.3.8 so far without success. My latest try consisted of

Code:

sudo apt-get update
sudo apt-get install python3-setuptools python3-pyqt5 python3-pip
wget https://download.electrum.org/3.3.5/Electrum-3.3.5.tar.gz
tar xvf Electrum-3.3.5.tar.gz

All appeared to work well (no error messages or warnings). I then tried to launch Electrum using Python.

Code:

python3 ~/Electrum-3.3.5/run_electrum
Traceback (most recent call last):
  File "/home/richard/Electrum-3.3.5/run_electrum", line 355, in

   os.unlink(lockfile)
PermissionError: [Errno 13] Permission denied: '/home/richard/.electrum/daemon'

I was at loss on what to do. I then got thinking about whether Electrum 3.3.8 is able to operate on a 32-bit computer, so before I go any further, is Electrum 3.3.8 designed to operate on a 32-bit computer under Lubuntu 18.04?

DAY 2

First I would like to thanks those who have given their time in trying to help me with this project. It is very much appreciated.

After yesterday, things where getting just too complicated for me. Today I have decided to try and get Electrum 3.3.6 working on my Lubuntu 16.04 desktop using the Appimage.

I have downloaded the Appimage and now have the folder Electrum-3.3.6 in my Home Folder. The Electrum-3.3.6 folder contains-

Folders:
contrib
electrum
Electrum.egg-info
PACKAGES

Files:
AUTHORS
Electrum Bitcoin Wallet
LICENCE
MANIFEST.in
PKG-INFO
README.rst
RELEASE-NOTES
run_electrum
setup.cfg
setup.py

I then double-click on the file Electrum Bitcoin Wallet. My hard disk works for about 20 seconds and then nothing.

Next was to double-click on the file run_electrum and then click on Execute. Hard disk works for about 5 seconds and then nothing.

Next was to double-click on the file run_electrum and then click on Execute in Terminal. The terminal window opens and text appears in the window. The window then closes before I can read the text.

How can I get Electrum 3.3.6 to work on my desktop?

Well look, there is a risk everywhere. I think that the credit card chargeback rate is about 20-25% and merchants take this risk on themselves. But you are also using a logic that person that paid $3 for a cup of coffee won't be doing a chargeback. It's not worth a risk.

We can use the same logic about the Bitcoin double spend. But if you are looking for a 100% solution, I guess that Bitcoin is not ready for paying a coffee like Ciyam has said above. Honestly I am not sure that this will be ever necessary in order for Bitcoin to succeed.

Mickeyb, you are thinking "western" here. The Philippines is not western. It is an under-developed third-world country. Less than 20% of adults (those 18yo and over) have a bank account. Less than 5% of all shop purchases are made with a credit/debit card.

Yes, a cup of coffee costs about USD2 to USD3 in the Philippines, but that is almost half a day's salary for most workers. A graduate engineer in the Philippines earns about USD15 per day. A shop salesperson earns about USD6.50 per 10 hour day.

The merchant, in this case, is hoping to just use an Android smartphone/tablet with say the Bitcoin Wallet ap installed to accept bitcoin payments. At the end of the day (or week) the merchant would use a Philippines bitcoin exchange to convert the received bitcoin into PHP and have it deposited directly into his bank account.

Initially, bitcoin sales are likely to be only one or two a month so capital outlay has to be kept very low. I can not see him investing even one centavo in anything more complicated.

From the replies that I have received in this thread, it looks like my response to the merchant's "double spend" concerns will be:

Quote

There is a very slight risk of a double spend, however you have a greater risk of one of your staff giving free food/coffee to their friend than you have of experiencing a double spend.

A double spend generally requires a customer to spend the exact same amount of bitcoin again within about 10 minutes of the first transaction and that second transaction must be confirmed on the blockchain ledger before the first transaction. None of this is easy to do in the current environment.

I need to keep my response fairly simple. Would this response be reasonable?

Quote from: shorena on October 01, 2015, 11:37:46 AM

I did a quick read up on mobile internet in the Philippines. Is the 3G connection that bad at the shop that you need to use WiFi? I suspect that this is reason the question came up in the first place, but I thought I make sure regardless. In most of Europe as well as north America most people would probably assume that customers have a 3G/4G data plan if they pay with bitcoin and dont bother at all.

More towards the actual topic, I would not try to block all but bitcoin on the port layer, but go to the application layer (7). If you have a router that can be run with open firmware solutions like tomato or OpenWRT it should be possible to create a bitcoin only WiFi. This might get tricky to setup though as I doubt there are ready to use filters like there are for other p2p traffic like torrents.

Maybe you can find a "good enough" solution by blocking HTTP(S) and mail as well as other commonly used services that generate a lot of traffic without actually having an airtight solution.

Shorena, 3G connection is readily available in the Philippines. The problem is the cost (hence the offer of free WiFi in the shop). Minimum connection fee to 3G can cost you PHP10 for 30 minutes minimum when the average salary is about PHP300 for a 10 hour day. Your internet connection using a smartphone can cost you almost as much per minute as you can earn per minute!

Thank you all who have replied.

As I said previously, an average sale could be a day's pay for an average (Filipino) worker. Not an insignificant amount. The shop employee handling the transaction would have just a basic (Filipino) high school education. This would mean that he/she can do no more than follow basic instructions - if your lucky.

Neither the sales person or the customer are going to wait for even the first confirmation. The merchant (shop) cannot set or easily check the transaction fee. Let's assume that the customer makes the purchase with zero transaction fee. (I know, Bitcoin Wallet does not allow this.)

So, the customer walks in, buys a coffee and food (take-out) with bitcoin zero transaction fee, then leaves the shop. How does this customer "double spend" his/her bitcoin?

What is "another spend that uses the same inputs"?
