Unmet dependencies errors updating kubuntu 18

Community

Hello,

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 ?

I believe it was mentioned in a previous topic with similar problems that the laptop and operating system are 64 bit versions and the version of Opera is 32 bit.

It was recommended to remove and preferably purge the 32 bit Opera version and to try installing a compatible 64 bit version.

It was very silly of me to install 386 version.
I tried to remove it, but got error :

# sudo apt-get remove  opera-stable:i386

Try:

sudo apt purge “opera-stable:i386”

Also try without the quotes if the above does not work.

Edit:
Just noticed that you already tried the above.

Try updating your system, fixing broken install and autoremove:

sudo apt update && sudo apt upgrade -y

sudo apt --fix-broken install

sudo apt update && sudo apt upgrade -y

sudo apt autoremove

sudo apt update && sudo apt upgrade -y
