如何显示所有apt-get Dpkg :: Options及其当前值？
有
apt-get -o Dpkg::Options::="--force-confnew" 和
apt-get -o Dpkg::Options::="--force-confold"
还有很多。
如何获取所有Dpkg::Options及其当前设置值的列表？
不幸的是，“apt-config dump”没有列出您正在寻找的dpkg选项。 “man dpkg”帮助我找到了这个命令“–force-help”，它更具体地针对你感兴趣的特定dpkg“force”选项，但不是一个全面的选项列表：
$ dpkg --force-help dpkg forcing options - control behaviour when problems found: warn but continue: --force-, ,... stop with error: --refuse- , ,... | --no-force- ,... Forcing things: [!] all Set all force options [*] downgrade Replace a package with a lower version configure-any Configure any package which may help this one hold Process incidental packages even when on hold not-root Try to (de)install things even when not root bad-path PATH is missing important programs, problems likely bad-verify Install a package even if it fails authenticity check bad-version Process even packages with wrong versions overwrite Overwrite a file from one package with another overwrite-diverted Overwrite a diverted file with an undiverted version [!] overwrite-dir Overwrite one package's directory with another's file [!] unsafe-io Do not perform safe I/O operations when unpacking [!] confnew Always use the new config files, don't prompt [!] confold Always use the old config files, don't prompt [!] confdef Use the default option for new config files if one is available, don't prompt.

可以使用。
