OK, Have been away for a day, back to the issue. My whole system crumbled - apparently after some cache period expired the whole interface went down, could not reach the settings anymore. So I had to reinstall.

I was a bit ahead of you and took the liberty to install a completely new system: raspbian buster which contains mono 6.0.0.319. That did not improve things, on the contrary.
I removed 6.0.0.319 and installed 5.18.0.225 according to your 5.x suggestion (which was NOT a singular operation).
That did NOT solve the problem.

So what I left with is reverting some old system. I had one backup image from a week ago, just before the problem. I'll put that back and copy the current Cumulus install over it. See what that does. I'll get back on this (currently restoring).

NB: During the whole process of trial and error, I got several times the following message:
Instellen van monodoc-http (4.2-3xamarin1+raspbian10b1) ...
Use of uninitialized value $libs in concatenation (.) or string at /usr/sbin/mono-xsp4-update line 216.
[ ok ] Restarting mono-xsp4 (via systemctl): mono-xsp4.service.
Maybe coincidence, maybe related.

It might be interesting to contact the development group of Mono and notify them of this issue.
You can't stay on Jessie or Stretch forever, the world turns.
If you don't and the problem does not magically go away in subsequent versions, you may have to solve it in CumulusMX itself, dates and strings are too important in Cumulus.

I will follow up with the result of my restore exercise.
After that I will stop this,it takes too much time.

Thanks Mark for the information. I have successfully reverted mono back to version 5.18.0.268. The install failed the first time but installed correctly the second time.

And now I see dashboard pages correctly with no 500 errors. However I cannot view the dashboard pages (timed out in the loading) on other devices on the LAN, which I will need to figure out.

OK, I managed to restore an 8 day old image from before I started the exercise and restored my cumulus backup from this morning. Everything is working as before (with: Mono JIT compiler version 4.6.2 (Debian 4.6.2.7+dfsg-1) ) just missed a day of data. I have learned something, hope you all have as well.

Certainly have learnt from this as I still quite new to using the pi and Debian. Good to hear you had success.

For another purpose (testing some hardware) I installed a brand new fresh download of Raspbian Buster from the official site (dated last month), installed mono-complete, and it installed version 5.18 for me?

Stranger Things?

I installed Buster from here (Raspbian Buster with desktop and recommended software).
Ran raspi-config to set everything up including locale for NL (did you use en_GB or another locale?).
Then downloaded/installed mono-complete from here (Raspbian 10).
This resulted in Mono version 6.0.0.319 (current stable version is already 327, stability apparently is rather overrated).
This was downloaded and installed 28/29th.

If that goes different elsewhere, it's beyond my comprehension. And maybe/probably everybody's.

And I have fixed the issue viewing the dashboard on devices on my LAN, so now have it back to the way it was. It was an IP address conflict of my network connection redundancy I have added to the pi when the sometimes unreliable network connection goes down (NBN: a new nationwide broadband upgrade rolled out as cheaply and fast as possible using existing ancient and outdated infrastructure and technology)

Only difference is I always use the headless lite version. But you'd think a distro is a distro and should be using the same repository sources :groan:

Raspbian Buster w/Desktop - 5.18 installed here as well.

I used to force a newer version prior to the Buster release for all to work properly, but Buster w/ the default 5.18 has worked perfectly for me.

Just for anyone who didn't know - to install the default version of Mono (currently 5.18):

Code: Select all

Sudo apt-get update
sudo apt-get install mono-complete

Please, mention the locale you are using in relation to this problem.

Just in case anyone wants to know how I reverted to the previous version of mono:

Code: Select all

sudo nano /etc/apt/sources.list.d/mono-official-stable.list
changed to:

Code: Select all

 deb https://download.mono-project.com/repo/debian/ stable-stretch/snapshots/5.18.0.268 main

Code: Select all

sudo apt-get remove mono-complete
sudo apt autoremove
sudo reboot
sudo apt-get update
sudo apt-get install mono-complete
