I suppose after installing of Opera in my kubuntu 18.04 I got errors:
$ sudo apt-get 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: opera-stable:i386 : PreDepends: apt-transport-https:i386 Recommends: pepperflashplugin-nonfree:i386 but it is not installable Recommends: chromium-codecs-ffmpeg-extra:i386 but it is not installed slimjet : Depends: libcurl3 but it is not installed or libcurl4 but it is not installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I am not sure if
apt --fix-broken install
is a safe way to fix it… How to fix these errors correctly ?
