我已经下载了 MEGAsync 的 debian 软件包并尝试在 Ubuntu 16.04 上安装：
sudo dpkg -i mega.deb
但它会引发这个错误：

然后我尝试sudo apt -f install修复这些缺失的依赖项并得到以下结果：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
The following packages will be REMOVED:
megasync
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 8.368 kB disk space will be freed.
Do you want to continue? [Y/n]
我怎样才能让它修复依赖关系并且不删除 MEGAsync？
还尝试sudo apt -y install ./megasync-xUbuntu_16.10_amd64.deb并得到：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'megasync' instead of './megasync-xUbuntu_16.10_amd64.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
megasync : Depends: libcrypto++6 but it is not installable
Depends: libqt5core5a (>= 5.6.0~beta) but 5.5.1+dfsg-16ubuntu7.5 is to be installed
Depends: libqt5svg5 (>= 5.6.0~beta) but 5.5.1-2build1 is to be installed

使文件可执行后，您只需通过 GUI 双击该文件即可。这是您可以选择的最快且最省心的选项，它让系统处理依赖项。如果您坚持使用 GUI 解决方案gdebi进行安装，其作用相同。因此，在您的情况下，请将sudo apt install -f其删除，然后执行以下操作。
# get the right package for your Ubuntu version 16.04 if this step fails
# because you not have 'wget' installed do 'sudo apt install wget' and retry
wget https://mega.nz/linux/MEGAsync/xUbuntu_16.04/amd64/megasync-xUbuntu_16.04_amd64.deb
#update the package archives
sudo apt update
#if the next step tells you that gdebi is already installed skip to the line after that
sudo apt install gdebi
# installing it with gdebi
sudo gdebi megasync-xUbuntu_16.04_amd64.deb
这应该安装所有必要的依赖项和包本身。

我所要做的就是
sudo apt-get install ~/Downloads/megasync-xUbuntu_18.04_amd64.deb
并且 apt 为我解决并安装了依赖项。
