jesus, people, run your wallets on live version of OS to prevent all viruses. If you dont know what live OS is you shouldn't be using crypto and for those using mobile phones for crypto purpose, well sorry a phone doesnt even come close to a computer.

 
that's great to hear there is nothing to worry, it was as root because I ran it on linux live form cd, installing, reinstalling, trying what's working or not. Hopefully this post helps others in the near future. Thank you for your help to all involved.

i was able to run imageapp but still get some invalids, so uncertain about using it for coins transactions:

mint mint # python3 -V
Python 3.6.3
mint mint # ./electrum-3.3.4-x86_64.AppImage
QStandardPaths: wrong ownership on runtime directory /run/user/999, 999 instead of 0
QApplication: invalid style override passed, ignoring it.


---and for 3.3.6 ver of appimage:

mint mint # ./electrum-3.3.6-x86_64.AppImage
/tmp/.mount_electrF8s0Lu/usr/lib/python3.6/site-packages/Cryptodome/Util/number.py:227: DeprecationWarning: invalid escape sequence \
  """
QStandardPaths: wrong ownership on runtime directory /run/user/999, 999 instead of 0
QApplication: invalid style override passed, ignoring it.
mint mint #

sorry, i ment 3.6.8

tried many times, upgraded pip's, python to latest 3.3.8 ver., nothing,  still cant run it.

I used to use electrum 3.2.2. with no problems on linux mint 18.3 x64xfce(sylvia)-live on laptop with pentium processor. I tried to run electrum 3.2.2 today and after making the electrum icon executable nothing happens I tried to click on it few times, nothing. Downloaded electrum 3.3.6 from electrum.org and after installing it same thing electrum fails to run so I cant even start inputting my seed. Any ideas.
