Gentoo 出现阻塞包问题

看来 clamav 包会阻止自身升级。 Portage 是最新的并且 Portage 树是同步的。有人知道如何通过 gentoo 中的阻止包来解决这个问题吗？

# emerge -uDpv clamav

These are the packages that would be merged, in order:

答案1

问题

了解您所看到的输出：

  1. mail-filter/qmail-scanner要求版本低于 0.99。请注意，您安装了 0.98.7 版本
  2. 新版本app-antivirus/clamav是0.99。
  3. Portage 是硬阻塞，app-antivirus/clamav因为 0.99 大于 0.98.7

使固定

mail-filter/qmail-scanner您需要2.08 以上的版本。既然没有，你有两种选择：

  1. 在 qmail-scanner 更新之前，不要打扰 clamav。看mail-filter/qmail-scanner-2.11 版本碰撞
  2. 修改mail-filter/qmailebuild中的a本地覆盖接受更新版本app-antivirus/clamav

答案2

解决方案：

emerge -C app-antivirus/clamav
emerge -1 app-antivirus/clamav
# continue with the update

问题：

  1. 较新的app-antivirus/clamav版本（0.99）阻止了DEPEND该部分中的所有先前版本
  2. 因此，如果前一个版本存在，则无法构建新版本
  3. portage本身无法应对这种情况，因为如果它卸载了旧版本并且新版本编译失败，你最终将根本没有clamav
  4. portage 向用户提供有关此问题的不友好消息

笔记：

mail-filter/qmail-scanner是无辜的
