从16.04升级到18.04要删除MariaDB服务器

Question

我有一个带有Ubuntu16.04的VPS，用作and服务器和Nextcloud。我想升级我的VPS到Ubuntu18.04。就像我一样

do-release-upgrade

它告诉我，如果我同意继续，它将完全删除MariaDB (服务器和客户端)。输出如下所示：

不再支持: cpp-5字体-nanum gcc-5-base gcc-6-base gucharmap libasan2 libgcc-5-dev libgtk2 2-perl libstdc++-5 dev ntp openjdk-8-jre subversion wvdial

另外，在Upgrade部分，我可以看到

下面是我安装的MariaDB包：

如何在保持安装MariaDB的同时升级Ubuntu？

Answer 1

它并没有完全摆脱MariaDB。它只是从10.0升级到10.1。升级的一部分意味着删除较旧的10.0包。

让它继续下去。

如果它真的摆脱了MariaDB，您将看到要删除的包列表中的包mariadb-server和mariadb-client (没有版本号)。

另一个线索是输出中的短语(was auto installed)。这意味着这些不是你--人类指定的包。相反，这些只是您specified...like mariadb-server和mariadb-client所依赖的其他东西。
