我一直在尝试安装Forticlient VPN在 LMDE 5 (Debian Bullseye) 上，它在 libappindicator1 的依赖项上失败。
阅读另一篇文章显然是根据我的理解，Mint 删除了该库，所以我继续安装它。
sudo apt-get install libappindicator1

好的。
现在我尝试安装 Foticlient VPN (7.0.0.0018)：

不知道从这里去哪里。这是一个全新安装，继我第一次尝试安装 libindicator7 的另一篇文章之后下载包，同样对于libappindicator1，它建议使用存储库上已有的包，所以我卸载了所有内容并使用命令行通过 apt-get 安装。同样的错误。
即使存在此错误，Forticlient VPN 仍然可以安装并运行，但会让您的库变得混乱，并且：
sudo apt-get install -f
强制您卸载 Forticlient。有什么线索吗？

尝试部分重新打包 forticlient VPN 并更改其依赖项。启动 shell 并导航到包含 .deb 的目录，然后执行以下操作：
mkdir -pv forticlient && cp -v forticlient_vpn*.deb forticlient && cd forticlient # Create a nice clean workspace
ar vx forticlient_vpn*.deb && tar vxf control.tar.?z # Unpack the deb
# Now, edit the dependencies in control to use libayatana-appindicator1 instead of libappindicator1
tar c {post,pre}{inst,rm} md5sums control | xz -z > control.tar.xz && ar rcs forticlient_vpn_mod.deb debian-binary control.tar.xz data.tar.?z # Repack the deb
然后，forticlient_vpm_mod.deb 即可安装。
