I wanna install Electrum 3.2.x in Centos 7. How can I do?
I tried methods written on https://electrum.org/#download
but I got this err msg "undefined symbol: FT_Get_Font_Format".

I can run only AppImage version of 3.3.4.
I am looking for the similar one of 3.2.x but I cannot find. 

My previous Electrum 3.2.2 's stuck at synchronizing.
Some people suggested me to update Electrum to the latest version.
Anyway, I still cannot use Electrum 3.3.4 because I cannot find the way to setup HTTP proxy.
There are only SOCKS4 and SOCKS5.
