我正在尝试从 Discover（KDE 等离子商店）在 Ubuntu 19.04 上安装 InkScape，但它显示错误：
Dependencies resolution failed
我尝试从 PPA 安装它
sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt install inkscape -y
但它仍然显示未满足的依赖关系。未满足此包或依赖项。
The following packages have unmet dependencies:
inkscape : Depends: libpoppler82 (>= 0.71.0) but it is not installable
Recommends: python-uniconvertor but it is not installable
E: Unable to correct problems, you have held broken packages.
怎么安装，没找到解决办法。任何帮助将不胜感激。
