The GUI blocks until network.set_parameters returns when switching servers, which waits for switch_to_interface, which used to wait until interface.close() returns. interface.close() tries to flush buffered writes to the wire, with a 30 sec timeout. If the server or the network connection is slow, flushing the buffer can take several seconds. In particular, servers running Fulcrum always seem to timeout in this case, freezing the GUI for 30 seconds (when switching away).

Getting started
===============
(*If you've come here looking to simply run Electrum,* `you may download it here`_.)
.. _you may download it here: https://electrum.org/#download
Electrum itself is pure Python, and so are most of the required dependencies,
but not everything. The following sections describe how to run from source, but here
is a TL;DR::
sudo apt-get install libsecp256k1-0
python3 -m pip install --user .[gui,crypto]
Not pure-python dependencies
----------------------------
If you want to use the Qt interface, install the Qt dependencies::
sudo apt-get install python3-pyqt5
For elliptic curve operations, `libsecp256k1`_ is a required dependency::
sudo apt-get install libsecp256k1-0
Alternatively, when running from a cloned repository, a script is provided to build
libsecp256k1 yourself::
sudo apt-get install automake libtool
./contrib/make_libsecp256k1.sh
Due to the need for fast symmetric ciphers, `cryptography`_ is required.
Install from your package manager (or from pip)::
sudo apt-get install python3-cryptography
If you would like hardware wallet support, see `this`_.

.. _pycryptodomex: https://github.com/Legrandin/pycryptodome
.. _cryptography: https://github.com/pyca/cryptography

Running from tar.gz
-------------------
If you downloaded the official package (tar.gz), you can run
Electrum from its root directory without installing it on your
system; all the pure python dependencies are included in the 'packages'
directory. To run Electrum from its root directory, just do::
./run_electrum
You can also install Electrum on your system, by running this command::
sudo apt-get install python3-setuptools python3-pip
python3 -m pip install --user .
This will download and install the Python dependencies used by
Electrum instead of using the 'packages' directory.
It will also place an executable named :code:`electrum` in :code:`~/.local/bin`,
so make sure that is on your :code:`PATH` variable.
Development version (git clone)
-------------------------------
Check out the code from GitHub::
git clone git://github.com/spesmilo/electrum.git
cd electrum
git submodule update --init
Run install (this should install dependencies)::
python3 -m pip install --user -e .
Create translations (optional)::
sudo apt-get install python-requests gettext
./contrib/pull_locale
Finally, to start Electrum::
./run_electrum
