memo for installing pycharm on ubuntu with snap-confine problem

  發覺Ubuntu 16.04/18.04下，
  若使用snap安裝pycharm
    snap install pycharm-community --classic
  老在執行時出現如下安全性問題 
    Snap-confine has elevated permissions and is not confined but should be
  
  這時，可改用如下1或2方法重新安裝 pycharm 解決執行不起來問題。
  1. umake安裝pycharm法
    sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
    sudo apt-get update
    sudo apt-get install ubuntu-make
    --
    umake ide pycharm
  其中，安裝路徑預設在~/.local/share/umake/...
  可以搬到全域路徑供大家共用:
   cd /usr/local/share
   sudo cp -pr ~/.local/share/umake .
   sudo ln -s /usr/local/share/umake/bin/jetbrains-pycharm-ce /usr/bin/pycharm
  這時就可用pycharm啟動ide整合開發環境
  
  2. 直接下載tar.gz安裝pycharm法
    https://www.jetbrains.com/pycharm/download/#section=linux

    cd /usr/local/share
    sudo tar zxvf pycharm-2019.2.3.tar.gz 
    sudo ln -s /usr/local/share/pycharm-2019.2.3/bin/pycharm.sh /usr/bin/pycharm
  這時就可用pycharm啟動ide整合開發環境
