google-cloud-sdk - 配置升级 google-cloud-sdk 失败

Question

在 Ubuntu 16.04 上升级 gcloud 在 postinst 配置上失败。 google-cloud-sdk 已经安装并使用，没有安装问题，但这会在配置阶段中止升级。问题似乎是 postinst 脚本正在使用 Python2 解释器执行 Python3 脚本，该脚本在 Python3 语法行上失败。

直接原因可能是内存不足。
尝试在升级前添加交换。

sudo dd if=/dev/zero of=/var/swap bs=2048 count=524288
sudo chmod 600 /var/swap
sudo mkswap /var/swap
sudo swapon /var/swap
sudo apt upgrade
