I was browsing Youtube and this video appeared to me, it seems easy to open channels, send/receive payments and buy online.
The costs are very low and the payments are very fast.

For beginners: there is no official version, verify that you are downloading from https://github.com/spesmilo/electrum and that you verify the signature.

Haven't played with toys for long time and seems like I have one now lol.
On my phone but when I get back to home, I will give it a go however I had plan to test it once they launch it in their official website but my interest is in the peak now.

Thanks for sharing and I will update in this thread soon.

Nice, a new toy to play with.  I think I'll set it up in my Ubuntu virtual box and play around with it this weekend.  It looks like there's a way to run it on Windows, but you have to use cUrl and install docker, and blah blah blah.  I don't want docker on my Win system, and if I'm going through all that shizzle I might as well just do it in Ubuntu.

I can't wait to see the new release with lightning built in.

[BitMaxz]

The video shows the alpha version it is still not the official one so the video shows the development test for Electrum lightning.

Where did you found the installation guide for Electrum 4.0 alpha version?
Does it seem I can't find it even in Github? Can you put the direct link here so that I can test this alpha version?

It seems that they deleted it someone shares the link from Reddit this must be the lightning open-sourced link https://github.com/spesmilo/electrum/tree/lightning but the link is not working anymore and it will show the 404 page(It means it was removed).

The instructions for the development version are near the bottom of the page linked by Royse777.

[AB de Royse777]

Okay now I have time to play with the toy.

For beginners: there is no official version, verify that you are downloading from https://github.com/spesmilo/electrum and that you verify the signature.

I just downloaded the files from github. Can you tell me where do I get the PGP key to verify it in here? Also which file I install, it seems a lot of files (in the folder electrum-master) which my windows do not recognize (I have no idea about python).

I gotta tell that this is the first time I am trying something from github.

Where did you found the installation guide for Electrum 4.0 alpha version?

As you can see, haven't install yet so I have no clue yet.

Edit:
Found some instructions in here: contrib/build-wine/README.md.
But it seems they have used some alien language LOL
Can anyone speak English to me about it :-D

[mocacinno]

@Royse777: you cloned the git repo, not the binaries... There are no signatures for these source files.
If you want to proceed, you'll have to create the binary for yourself. I don't see any documentation as to how to compile the binary in a windows environment, but maybe you can run linux as a virtual machine on your desktop in order to compile the sourcecode (there's a complete how-to on building windows binaries from linux here: https://github.com/spesmilo/electrum/tree/master/contrib/build-wine)?

An other option is that you ask somebody you really, really, really, really trust to build the binary for you... But even then, i'd probably only run it on the testnet inside a jail (or on a computer that's not being used for anything else, contains no other user data, and will be scratched afterwards)

[AB de Royse777]

Thanks mocacinno.

(there's a complete how-to on building windows binaries from linux here: https://github.com/spesmilo/electrum/tree/master/contrib/build-wine)?

This is what I was talking about to in my last post with the edit. I guess you missed it, not your fault.

I really do not have this option which means I will need to do some studies about it. Will update you lot once I have a question.

[mocacinno]

@Royse777, if you're a beginner, and you want to save yourself a headache messing with docker, cross compiling,... It might be better to install the latest ubuntu on a clean virtual machine (like virtualbox).

Then follow https://github.com/spesmilo/electrum


Basically
sudo apt-get install python3-pyqt5 python3-pip python3-setuptools protobuf-compiler
git clone git://github.com/spesmilo/electrum.git
cd electrum
git submodule update --init
python3 -m pip install .[fast]
protoc --proto_path=electrum --python_out=electrum electrum/paymentrequest.proto
./run_electrum

Tried these command in Linux lite but the sad part I'm stuck on upgrading the python to 3.6.2 the reason why I want to upgrade the python it's because the python version installed is 3.5.2 but the required python is 3.6.1.



I'll update this soon and maybe I can find a way to install the Python 3.6.1 on the Linux lite version.

Commands that I use recently.

Code:

sudo apt-get install python3-pyqt5 python3-pip python3-setuptools protobuf-compiler
sudo apt install git
git clone git://github.com/spesmilo/electrum.git
cd electrum
git submodule update --init
python3 -m pip install .[fast]

I just added the sudo apt install git because I can't make a git clone now it works fine but stuck on python-pip install.

This part isn't too hard, all you need to do is compile Python 3.6 from source then install it. Check this guide https://realpython.com/installing-python/#compiling-python-from-source

You also could add 3rd-party repository which serve newer version of Python, but i don't know how to do it on your linux distro.

Yeah, I'm following the same guide from here http://devopspy.com/python/install-python-3-6-ubuntu-lts/ with method 2.
but I'm stuck again with "$ sudo make -j8" and it seems the error is "full disk" I think I will need to increase the VirtualBox space. I thought that it won't download too many resources and packages but after I use the command above it eat so much space on Virtualbox space. Anyway, I'll update this again soon. Too bad I have slow internet connection.

Do you have any idea for another way to compile it for windows instead? I don't have much space on my laptop after I applied the last step installing python.

[dkbit98]

My suggestion is to install some ligth version of Windows OS in VirtualBox if you have problem with installing Linux wallet.
I had problem with install one app on Ubuntu and I had to switch back to Windows.
I hope Electrum will work, and we can soon see full version, but I do expect lot of bugs.

My laptop is windows so I don't need to install it in VirtualBox the reason why I use VirtualBox it's because you can only compile the Electrum Alpha version with Linux according to this https://github.com/spesmilo/electrum

Unless you know how to compile it on windows OS? It will help us if you can share it here.

[HCP]

Just FYI, today I installed a fresh copy of Ubuntu (18.04.3) into Oracle VirtualBox... then basically followed the instructions on the Electrum Github under Development Version step by step...

I literally copy/pasted the commands into the Ubuntu terminal window, with the only modification being that I used sudo -H python3 -m pip install .[fast] as when I originally tried it with just "python3 -m pip install .[fast]", it spat out a "permission denied" at the end.

NOTE: I also had to install git, python3-pip and curl (and possibly one or two other things that I've forgotten)... as I think I chose the "minimal" Ubuntu install.

Anyway, after I had Electrum cloned and "installed"... I then followed the instructions on the contrib/build-wine/README.md page... again, copy/pasting the commands as shown to install docker, build the image and then build the Windows binaries.

et voilà...



Now I just have to work out how to get it to build the 4.0.0a branch... which doesn't seem to exist any more

But oddly, when I run Electrum within the VirtualBox, it runs 4.0.0a??!?

[mocacinno]

Now I just have to work out how to get it to checkout the 4.0.0a branch... which doesn't seem to exist any more

Code:

git checkout master
cat electrum/version.py

[HCP]

yeah... wrong wording on my behalf, I didn't mean checkout... I meant build... if I look in my "fresh clone" directory... cat electrum/version.py shows version 4.0.0.a0, but for some reason, when running the build.sh, it is only building 3.3.8 version??!?

EDIT: disregard, it's just naming the output file incorrectly... it is in fact building the 4.0.0a0 version:


I transferred the "3.3.8" portable .exe file out of the Ubuntu VirtualBox and ran it on the Windows 10 host

[BitMaxz]

After resize the space from VirtualBox, AFAIK you need to configure the partition to use all free space.

P.S. compile from source will use 100% CPU and it took some time (about 30 minutes on old PC with 2 core)

default.

Yeah, done on resizing the virtual box using command prompt after that it shows something unallocated space and tried to restart the virtual box and the laptop(I thought the unallocated space will merge automatically) but after that my laptop shows bluescreen of death.

Something issue on both tcpip.sys and ntoskrnl.exe they randomly showing every time I restart.
Anyway, my laptop fixed just now using the "chkdsk /f /r". I'm not going to test it again with my laptop.

I think it's better to rent a Linux VPS/RDP to install and test the Electrum alpha version rather than using my slow laptop.

Can I have a copy of the portable one for Windows? I would love to test it on windows 7. Please Pm me the link thanks.


I got the portable one from HCP and it's working fine to me.

Since this is a virtualbox install, the solution is simpler than you think. Rather than "Linux Lite", you should install Lubuntu 19.10, which happens to come with Python 3.7.5

Why Lubuntu? Linux Lite IS Lubuntu with extra packages pre-installed. Contrary to what the name suggests, it isn't light. So you save space and time using Lubuntu rather than Lite.

In the earlier Ubuntus you can probably upgrade python also by adding a PPA, but this might be trickier than just wiping your image since its a virtual machine anyway. If you use the 32bit version, you can probably use 1g ram virtual machine just fine, maybe less if its just playing with Electrum.

Oh and that -j8 is the number of threads for the compiler, it depends on what cpu you have and if you want to use all of them (i don't think thats a good idea a vm, i never assign all my threads to a vm). So if you launched a VM with 2 threads (because your cpu has 4 cores), you shouldn't be using -j8 (it would just try use the 2 threads 4times). If in doubt omit the -j option its not needed.

I'm getting the same issue with names, but I have not been able to confirm if I'm actually building 4.0.0a0.  Trying to run the portable version on my Win10 machine I get an error saying the file cannot be found.  I tried running it right from the desktop, so I don't know how that's possible.  Do I need to install some python run environment something or other in Windows?
