New Version of Mono-project - Can't Update

[DuaneT]

There is a new version of the Mono-project Version 6.6.0.161 (the open source .net software on the raspberry). Whenever i try and upgrade I get a timeout error. Has anyone been successful at upgrading? And I guess the other question is, is anyone else regularly updating the OS software on their Pi?

Have current version of Mono installed on an ARM CPU and Intel CPU. It's been a while since I have installed it.

How are you installing the new version?

I installed Mono via the guide on the Mono Website here ==> Mono Install

Updates to this Mono version came from updating and installing upgrade.

1 - sudo apt update *
2 - sudo apt upgrade **

* ==> sees the update to Mono
**==> updates Mono

Pete, My original install came from the HS3PI install (it was in their image). I am now using sudo apt-get update then sudo apt-get upgrade. After update/upgrade says there are 165 packages to upgrade (new version of Mono .161) . The problem is every time I try and do the upgrade the system times out when trying to do the download then update.. This causes the failure. Here are the upgrade "results"

I have tried the --fix-missing but nothing new happens. I also can't find a mirror for the Mono-project to try another source. Any ideas?

The Zee's that have / had the built Mono have become an issue because you cannot update these. You have to remove the old mono first which is a PITA.

After removal then try the install per the installation guide on the mono site.

You can try the following:

1 - sudo apt-get purge mono-runtime
2 - sudo apt-get purge mono-complete
3 - sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1
4 - sudo rm -rf usr/lib/mono /usr/local/bin/mono /usr/local/etc/mono /usr/local/lib/mono
5 - sudo apt-get purge libmono* cli-common mono-runtime
6 - sudo apt-get autoremove Then test if you have mono installed by typing mono -V

Or

Download latest Zee image and write it to a new SD card then copy your Homeseer directory from the current SD card to the new image SD card. Time involved might be shorter to create a new image and restore Homeseer to it. Homeseer resides in the /usr/local/HomeSeer directory.

The links above may be incorrect or your DNS is messing up.

Strange as it sounds I figured out a solution. I'm not sure how or why it works but it did. All I did was change the repository from the named version to the ip address. Once I did that the update literally took 45 seconds to update. So it looks like my problem was a DNS resolver issue (or an IP6 vs IP4 issue), Here is what my /etc/apt/stable.list.d/mono-official-stable.list file now looks like


# deb https://download.mono-project.com/repo/debian stable-raspbianstretch main
deb https://72.21.81.200/repo/debian stable-raspbianstretch main

I got the ip address by doing a nslookup on a windows machine to find the address.

Thanks to all for helping with this.
