I was able to successfully install it by disabling IPv6 as you told me.

[Method]
①Open sysctl.conf
$ sudo vi/etc/sysctl.conf

以下 Add the following
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6 = 1

sSave and close sysctl.conf

設定 Reflect settings
$ sudo-p

IPvVerify that IPv6 does not exist
$ ip a

ggem update --system

That's all I was able to update.
