I can't install without forcing.

I tried deleting all the mongo source lists and readded them. However, I think you have to wrap removing and re-adding the source lists with apt-get update, which is why it did not fix it the first time you tried this. I don't think adding "[ arch=amd64,arm64 ]" fixed it either. brendanball commented on Fri, 12 May 2017 14:52:36 +0000: so that seems to have fixed this server. The only difference that I can see is that I wasn't specifying [ arch=amd64,arm64 ] in the apt source but I can't see how that would've broken anything. Thanks anyway, I guess this is still not reproducible. If I uninstall mongo and add the apt source that it had previously it still works if I reinstall it again. brian.samek commented on Fri, 12 May 2017 14:24:36 +0000: Hi brendanball, Assuming you are running MongoDB 3.4, could you try running these steps, and paste their output? sudo rm /etc/apt/sources.list.d/mongodb-org-3.4.list sudo apt-get update echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list sudo apt-get update sudo apt-get install -y mongodb-org brendanball commented on Wed, 10 May 2017 09:42:10 +0000: I have the same problem on one of my servers, also running ubuntu 16.04. I tried deleting all mongo keys from apt, readded the key. I tried deleting all the mongo source lists and readded them. I tried cleaning the apt cache with apt-get clean After all of this I still get the same error. I didn't experience this issue on an almost identical server which should have all of the same config. I don't want to force install so I don't know how else to fix this. Possibly we can reopen this issue? If there is any more info you can get from me to diagnose the issue let me know. brian.samek commented on Tue, 13 Dec 2016 19:39:18 +0000: I'm going to close as can't repro. If this reproduces or we learn more about the user's problem, we can debug further.
