如何阻止dist-upgrade删除MariaDB？

在Partial升级中提出了类似的问题- 为什么删除MariaDB？ 。 这个问题的答案基本上是表明dist-upgrade是问题所在。 这个问题是询问是否有一些解决方法（或修复）。

有时需要进行dist-upgrade而不仅仅是升级。

我们可以在sources.list（或其他地方）中更改某些内容，告诉Ubuntu不要删除MariaDB吗？

现在MariaDB已经更新了他们的PPA：

Answer 1

 破解mysql-common：amd64在mysql-client-5.1上rest[amd64]（无）
   冲突//打破版本10.0.7 + maria-1~对于mariadb-client-10.0是精确的，但这不是InstVer，忽略
  考虑到mariadb-client-5.5：amd64 2作为mysql-common的解决方案：amd64 8
   将mariadb-client-5.5：amd64添加到删除列表中 

可以看出，如果您尝试升级mysql，MariaDB会中断。 您应该暂时只依赖sudo apt-get upgrade来防止删除MariaDB。

Answer 2

MariaDB在他们关于安装deb软件包的文章中介绍了这一点，修复它的最佳方法是通过固定MariaDB repo。 您可以按照以下说明操作： https ： //mariadb.com/kb/en/installing-mariadb-deb-files/#pinning-the-mariadb-repository （如果您向上滚动它们也可以解释它为什么会发生）
