Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
mysql-common : Conflicts: mysql-server-8.0 but 8.0.34-0ubuntu0.22.04.1 is to be installed
mysql-server-8.0 : Depends: mysql-client-8.0 (>= 8.0.34-0ubuntu0.22.04.1) but it is not installable

我有未滿足的依賴項，即使它們已被刪除。我不明白。
謝謝！

我重新安裝了舊快照以保持我的網站在線。於是又安裝了舊版的mysql8.0。我得到了未滿足的依賴關係。

對於第一次恢復預設儲存庫為了傑米。
認同
grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d/
這個倉庫在哪裡 repo.mysql.com處於活動狀態並將其刪除。
sudo apt -s purge $(dpkg -l | grep mysql | awk '{print $2}')
這首先是模擬。為了徹底刪除。
sudo apt purge $(dpkg -l | grep mysql | awk '{print $2}')
刷新包緩存。
sudo apt update
然後再試一次。
