更新：添加why-not输出build议（ why输出也）。
# aptitude why-not libwbclient0 Unable to find a reason to remove libwbclient0.` `why` gives this reasoning. # aptitude why libwbclient0 i nagios-plugins-standard Recommends smbclient p smbclient Depends samba-libs (= 2:4.3.11+dfsg-0ubuntu0.14.04.11) p samba-libs Depends libwbclient0 (>= 2:4.0.3+dfsg1)
为什么aptitude upgrade无法在apt-get upgrade愿意执行的情况下实际升级软件包？ 据我所知，这两个命令在function上应该是一样的，但显然他们不同意。 任何人都可以解释如何find问题在这里，为什么它适用于一个命令，但不是另一个？
