I have a problem after apt upgrade ang get this message:

 The following packages have unmet dependencies.

 libnvidia-ifr1-390 : Depends: libnvidia-gl-390 but it is not installed

 libnvidia-ifr1-390:i386 : Depends: libnvidia-gl-390:i386 but it is not installed

 nvidia-driver-390 : Depends: libnvidia-gl-390 (= 390.87-0ubuntu0~gpu18.04.1) but it is not installed

                     Recommends: libnvidia-gl-390:i386 (= 390.87-0ubuntu0~gpu18.04.1)

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

After that I try apt --fix-broken install, but I get:

dpkg-divert: error: mismatch on package

E: Sub-process /usr/bin/dpkg returned an error code (1)

Then I try solution from
how to fix this apt problem on ubuntu 18.04 LTS?

sudo rm /var/cache/apt/archives/libnvidia-gl-390_390.87-0ubuntu0~gpu18.04.1_i386.deb

sudo rm /var/cache/apt/archives/libnvidia-gl-390_390.87-0ubuntu0~gpu18.04.1_amd64.deb

then to erase all of the downloaded files in your cache.

sudo apt-get clean

sudo apt-get autoremove && sudo apt-get autoclean

And again I got:

The following packages have unmet dependencies.

 libnvidia-ifr1-390 : Depends: libnvidia-gl-390 but it is not installed

 libnvidia-ifr1-390:i386 : Depends: libnvidia-gl-390:i386 but it is not installed

 nvidia-driver-390 : Depends: libnvidia-gl-390 (= 390.87-0ubuntu0~gpu18.04.1) but it is not installed

                     Recommends: libnvidia-gl-390:i386 (= 390.87-0ubuntu0~gpu18.04.1)

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I update ubuntu from version 16.04 to 18.04 3 weeks ago - but this problem appeared two days ago.

Can anyone help?

It most likely didn't install correctly.
I'd probably remove the packages without dependencies like so:

sudo dpkg -r libnvidia-ifr1-390

sudo dpkg -r libnvidia-ifr1-390:i386

sudo dpkg -r nvidia-driver-390

Using those commands should free up apt-get, now you can install the dependencies and reinstall the driver: (This should install the dependencies automatically)

sudo apt-get install nvidia-driver-390

And if the same thing happens again, try this: (This installs the listed dependencies and the driver)

sudo apt-get install libnvidia-gl-390:i386

sudo apt-get install libnvidia-gl-390

sudo apt-get install nvidia-driver-390

Or this: (This uninstalls and purges anything installed related to Nvidia and installs the driver while also deleting local copies of packages to download it again)

sudo apt-get clean

sudo apt-get purge nvidia*

sudo apt-get autoremove --purge

sudo apt-get install nvidia-driver-390

OK I'm in the same boat as this. I upgraded from 16.04 to 18.04 Mate. When I try to do this: apt --fix-broken install. I get this:

dpkg: error processing archive /var/cache/apt/archives/libnvidia-gl-    390_390.87-0ubuntu0~gpu18.04.1_amd64.deb (--unpack):

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

When I try to purge any with nvidia I get a similar error. What can I try. PS I hate Nvidia with a passion.

Exact error I get is this:
