我正在尝试安装libgdal-dev
:
sudo apt-get install libgdal-dev
但它有未满足的依赖关系:Depends: libpng-dev
但其本身无法安装,因为:
libpng12-dev : Depends: libpng12-0 (= 1.2.54-1ubuntu1.1) but 1.2.54-5x0~ppa is to be installed
该软件包从以下位置安装ppa
:
dpkg -s libpng12-0 | grep ^Maintainer
Maintainer: Otto Meier <[email protected]>
(通过)
我想保留它苯甲酸因为它提供了 GIMP 2.9。
问题:
我该如何安装
libpng12-dev
和libgdal-dev
(可能忽略或手动更改某些依赖项)?或者一般来说:当依赖项已从 PPA 安装在另一个版本中时,如何安装软件包?
(提示:使用 Snap 安装 GIMP 既不是首选也不可能的)
我尝试过的:
我安装了libpng12-dev
忽略libpng12-0
依赖性(通过):
apt download libpng12-dev
sudo dpkg --ignore-depends=libpng12-0 -i libpng12-dev_1.2.54-1ubuntu1.1_amd64.deb
这有效。
此外,libgdal-dev
仍然有 unmnet 依赖项,因此我做了同样的事情:
sudo apt install libgdal-dev
sudo dpkg --ignore-depends=libpng12-0 -i libgdal-dev_2.2.2+dfsg-1~xenial1_amd64.deb #png12-dev_1.2.54-1ubuntu1.1_amd64.deb
dpkg: dependency problems prevent configuration of libgdal-dev:
libgdal-dev depends on libarmadillo-dev; however:
Package libarmadillo-dev is not installed.
libgdal-dev depends on libcurl4-gnutls-dev | libcurl-ssl-dev; however:
Package libcurl4-gnutls-dev is not installed.
Package libcurl-ssl-dev is not installed.
libgdal-dev depends on libdap-dev; however:
Package libdap-dev is not installed.
libgdal-dev depends on libepsilon-dev; however:
Package libepsilon-dev is not installed.
libgdal-dev depends on libfreexl-dev; however:
Package libfreexl-dev is not installed.
libgdal-dev depends on libfyba-dev; however:
Package libfyba-dev is not installed.
libgdal-dev depends on libgeos-dev; however:
Package libgeos-dev is not installed.
libgdal-dev depends on libgeotiff-dev; however:
Package libgeotiff-dev is not installed.
libgdal-dev depends on libgif-dev; however:
Package libgif-dev is not installed.
libgdal-dev depends on libhdf4-alt-dev; however:
Package libhdf4-alt-dev is not installed
因此,我在这里停下来并再次修复了这种情况:
sudo dpkg -r libgdal-dev
sudo dpkg -r libpng12-dev
答案1
@dsstorefile1 给出了正确的提示来解决我的问题:
我在问题中链接的 ppa曾是当我安装它时,它是为 16.04 制作的,但是它发生了变化并且维护者删除了包括xenial
在内的大多数软件包libpng12-0
。
所以我是这样解决这个问题的:
使用以下命令删除 ppa
ppa-purge
:sudo ppa-purge ppa:otto-kesselgulasch/gimp
将软件包降级
libpng12-0
为官方存储库中的版本:sudo apt install libpng12-0=1.2.54-1ubuntu1.1
安装
libgdal-dev
:sudo apt install libgdal-dev
我还注意到,以下软件包也是该 ppa 的残留:
libbabl-0.1-0
libgegl-0.3-0
liblcms2
libwebp6
因此,我还降级/删除了这些:
sudo apt install libbabl-0.1-0=0.1.16-1
sudo apt install libgegl-0.3-0=0.3.4-1ubuntu2
sudo apt install liblcms2-2=2.6-3ubuntu2
sudo apt remove libwebp6 #no candidate from repos
