我尝试升级并收到以下错误：
$ sudo apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libgles-dev : Depends: libgles1 (= 1.3.0-7~kisak~b) but it is not installed
qtbase5-dev : Depends: libgles2-mesa-dev but it is not installed or
libgles2-dev but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
然后实施建议：
$ sudo apt --fix-broken install
