debian系统解决包依赖问题的神器aptitude
最近在玩OPI的时候遇到了一个包因为各种依赖问题死活装不上.苦搜很久找到这个aptitude.
基于debain衍生的各种操作系统比较常用包管理器是apt,不过apt在遇到依赖问题的时候处理得不是很好.
就像这样:
The following packages have unmet dependencies:
build-essential : Depends: libc6-dev but it is not going to be installed or
libc-dev
g++ : Depends: g++-4.9 (>= 4.6.4-1~) but it is not going to be installed
libboost-dev : Depends: libboost1.55-dev but it is not going to be installed
libfreetype6-dev : Depends: libc6-dev but it is not going to be installed or
libc-dev
libncurses5-dev : Depends: libc6-dev but it is not going to be installed or
libc-dev
libpam0g-dev : Depends: libc6-dev but it is not going to be installed or
libc-dev
libpcre3-dev : Depends: libc6-dev but it is not going to be installed
libpng12-dev : Depends: libpng12-0 (= 1.2.50-2+deb8u3) but 1.2.51-0ubuntu3 is to be installed
libxml2-dev : Depends: libxml2 (= 2.9.1+dfsg1-5+deb8u6) but 2.9.2+dfsg1-3 is to be installed
zlib1g-dev : Depends: zlib1g (= 1:1.2.8.dfsg-2) but 1:1.2.8.dfsg-2ubuntu1 is to be installed
Depends: libc6-dev but it is not going to be installed or
libc-dev
E: Unable to correct problems, you have held broken packages.
apt会报个错然后就不管了,你自己解决
而aptitude会自动找出包依赖的问题,给提供解决方案:
The following packages have unmet dependencies:
libc6-dev : Depends: libc6 (= 2.19-18+deb8u10) but 2.21-0ubuntu4 is installed.
libc-dev-bin : Depends: libc6 (< 2.20) but 2.21-0ubuntu4 is installed.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) libc-dev-bin [Not Installed]
2) libc6-dev [Not Installed]
Accept this solution? [Y/n/q/?] n
The following actions will resolve these dependencies:
Upgrade the following packages:
1) locales [2.13+git20120306-19 (now) -> 2.19-18+deb8u10 (oldstable)]
Downgrade the following packages:
2) libc-bin [2.21-0ubuntu4 (now) -> 2.19-18+deb8u10 (oldstable)]
3) libc6 [2.21-0ubuntu4 (now) -> 2.19-18+deb8u10 (oldstable)]
首先给出了1个方案:
1) libc-dev-bin [Not Installed]
2) libc6-dev [Not Installed]
问我是否接受,我答n以后给了第二个方案
1) locales [2.13+git20120306-19 (now) -> 2.19-18+deb8u10 (oldstable)]
Downgrade the following packages:
2) libc-bin [2.21-0ubuntu4 (now) -> 2.19-18+deb8u10 (oldstable)]
3) libc6 [2.21-0ubuntu4 (now) -> 2.19-18+deb8u10 (oldstable)]
自动解决依赖问题!
用这个命令安装aptitude:
sudo apt install -y aptitude
有个别情况需要多试几种方案
