Survey for Linux users, which version of Mono do you have installed?

An informal survey. We’re looking at upgrading the targeted .NET frameworks and would like to get an idea of the version of Mono people currently have installed.


Please run the command below and report the version here:
mono --version

Is the mono version reported in the usage statistics?

Where would I find those stats?

I’m not sure…but the usage reporter code does appear to capture the mono version.

Debian Buster -
Synology NAS - 4.6.2

Ubuntu Xenial 4.2.1
and then some text to satisfy the length on posting requirement…

Fedora 30 Server:
Debian Buster (Raspbian):

Maybe CLRVersion falls to the same fate as (presumably) AppVersion? Regardless, it’d also be nice to know what Duplicati people are running, especially including actual usage of Canary and Experimental, which would give some clue as to whether a given whatever has had enough (or any) outside tests yet. Having a more capable query ability might answer questions like “Who’s on this new canary backend?”
EDIT: Numerically (not personally) speaking, of course.

(above refers to Duplicati versions, but possibly extends to other ones)

If anybody wants to look at (or look at enhancing) some Python code, the usage reporter source is here.

Do you by any chance have OneDrive to test with? I’m wondering whether this report is reproducible or not:

EDIT: put back some auto-deleted text and added versions

Browsing my /var/log/dpkg.log history, it looks like mine was which seems right even today for Linux Mint 18.1 which derives from Ubuntu Xenial Xerus (16.04LTS) and uses its packages.

Since then, I’ve updated to test presence (or absence) of issues like Duplicati does not start up #3572 and Error with Debian mono 5.18 #3620, or to attempt to build. Above says Xenial 4.2.1 would be fine, if I had it.

Two instances, same on both:

  • On Debian 10.0/buster
  • And on Synology DSM 6.2.2

Thank you for all the responses. It’s quite helpful.

I’m on Ubuntu 18.04, it’s 4.6.2 (Debian
