Original GitHub issue: https://github.com/electerm/electerm/issues/1363

Electerm version: 0.27.65-linux-x86_64

Operating system: CentOS Linux release 7.6.1810 (Core)

# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core)
# gnome-shell --version
GNOME Shell 3.28.3

Expected Behavior

About 5 mouth ago, I installed electerm-0.27.12-linux-x86_64 using the followed command.

# rpm -ivh electerm-0.27.12-linux-x86_64.rpm

It went ok.
I think it should be ok to upgrade eleterm to 0.27.65-linux-x86_64 with command:

# rpm -ivh electerm-0.27.65-linux-x86_64.rpm

Current Behavior

I uninstall electerm-0.27.12. But when I start to install electerm-0.27.65, there are some errors.

# rpm -e electerm-0.27.65-371.x86_64
# rpm -ivh electerm-0.27.65-linux-x86_64.rpm

How about the tar.gz release https://github.com/electerm/electerm/releases/download/v0.27.65/electerm-0.27.65-linux-x64.tar.gz, is it work? Can you try it?

@zxdong262
I try to use the electerm-0.27.65-linux-x64.tar.gz. I run " ./electerm" command when decompress the .tar.gz file because I can't find the icon on the destop.

# tar -zxvf electerm-0.27.65-linux-x64.tar.gz
$ cd tar -zxvf electerm-0.27.65-linux-x64.tar.gz
$ ./electerm

You need to make sure that /volumea/chrome_download/electerm-0.27.65-linux-x64/chrome-sandbox is owned by root and has mode 4755.

so I change chrome-sandbox mode 4755, and try "./electerm" again. But there is a A JavaScript error .

# chmod 4755 chrome-sandbox
$ ./electerm

Yes, it apper the same. But I don't know how to fix it. Maybe I will update my gnome someday.
