[ubuntu19.10] snap错误has install-snap change in progress

使用软件商店安装时遇到snap has install-snap change in progress问题

原因是之前的安装错误终止，使得现在的安装无法进行，解决方案：

终端输入：

snap changes

我们可以看到ID号为3，6，7的需要终止：

cangye@cangye-Aspire-F5-572G:~$ snap changes
ID   Status  Spawn               Ready               Summary

5    Done    today at 07:03 CST  today at 07:03 CST  Remove "code" snap

7    Doing   today at 07:57 CST  -                   Install "pycharm-professional" snap

于是输入以下命令即可

sudo snap abort ID号
