升级到最后出现报错：

Processing triggers for libc-bin (2.28.17-1+eagle) ...
Errors were encountered while processing:
grub-efi-amd64-signed
E: Sub-process /usr/bin/dpkg returned an error code (1)

前面也有一条关于grub-efi-amd64-signed的报错

dpkg: error processing package grub-efi-amd64-signed (--configure):
installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

另外还提示找不到rootb的uuid，检查了/etc/fstab，没有rootb

grub-efi-amd64-signed干么的？这算升级成功吗？有没有其他影响？
