Are you talking about the python compatibility issues? There's outdated python repos on a lot of Linux distros and I tried installing it from source but it just kept failing for random reasons so if that's the sane issue as you then I suggest you wait (wasabi was previously suggested but afaik armory needs bitcoin core).
Yup, that's the issue I was having.
Just tested it with Debian stable (testing has newer versions), and it seems it really only has python 3.5.3 in its repositories while electrum needs python 3.6.
However, it can be installed this way (python 3.6.3; just tested on debian stable):
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
tar xvf Python-3.6.3.tgz
cd Python-3.6.3
./configure --enable-optimizations
make -j8
sudo make altinstall
You will have
python3 (3.5.3) and python3.6 installed.
Then you'll need to install pyqt5 via:
sudo pip3.6 install pyqt5
Afterwards electrum can be run using:
inside of the electrum directory.
Of course this also works with newer versions of python.
I will give this a try.
