I've just run an update on my system, and I have an install error for the msbuild package.

After run sudo apt update && sudo apt upgrade && sudo apt dist-upgrade, I got this error message:

I've also try to install with sudo dpkg -i --force-depends /var/cache/apt/archives/msbuild_1%3a16.0+xamarinxplat.2019.05.07.15.32-0xamarin2+ubuntu1804b1_all.deb. Then I got almost the same error message:

  • Why don't you use the official dotnet packages?

This happened to me on Both on Ubuntu and Debian 10.

This command fixed the issue for me:

sudo apt-get -o Dpkg::Options::="--force-overwrite" -f install

for me it worked in 2 steps:

apt upgrade -y
sudo apt-get -o Dpkg::Options::="--force-overwrite" upgrade
sudo dpkg -i --force-depends /var/cache/apt/archives/msbuild_1%3a16.0+xamarinxplat.2019.05.07.15.32-0xamarin2+ubuntu1804b1_all.deb
