处理过程中遇到错误:grub-efi-amd64 64-签名- Ubuntu 20.04.1

Question

我已经更新了我的ubuntu服务器从16.xx到18.xx到现在Ubuntu20.04.1LTS。

我试过了

sudo apt-get purge grub\*
sudo apt-get install grub-efi
sudo apt-get autoremove
sudo update-grub

但还是犯了错误。

我试过了

sudo apt-get -f install

但还是犯了错误。

我不知道下一步该做什么，因为所有的谷歌搜索都给了我很少的解决方案，但这些解决方案都不起作用。
