我剛剛啟動軟體更新程式並在安裝更新的軟體時收到通知：
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
Transaction failed: Package dependencies cannot be resolvedI
The following packages have unmet dependencies:
grub-efi-amd64-signed: Depends: grub2-common (>= 2.02+dfsg1-5) but 2.04-1ubuntu26.15 is to be installed
請告訴我如何解決這個問題。
