@rajasingh012 Fist, you need to add the Mono Project GPG signing key and the package repository to your system, as seen here: http://www.mono- project.com/docs/getting-started/install/linux/#debian-ubuntu-and- derivatives
Then, you have to pin the package to not install from ubuntu repo, which provides a higher version. Edit file /etc/apt/preferences and put the following: Package: monodevelop Pin: origin archive.ubuntu.com Pin-Priority: -1 Run apt-get update Finally, you can downgrade with: # sudo apt install monodevelop=5.10.0.871-0xamarin2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563090 Title: monodevelop 5.10.0.871-2 has broken asp.net support/addin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/monodevelop/+bug/1563090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
