This is very sudden. I had to reboot the Ubuntu machine, and after reboot I noticed the Duplicati “tray icon” missing. So I tried to restart Duplicati from command line, but the command “duplicati” tells me: “Server is not responding. Is it running?”
I have only ever used Duplicati in user mode, and I have not updated any Ubuntu packages recently. I am currently using Duplicati version 184.108.40.206. I already tried uninstalling duplicati and mono-devel and reinstalling the both, but that didn’t help.
Now, I don’t know how to trouble-shoot this. What can I do?
What version of mono is it?
$ mono --version
Mono JIT compiler version 220.127.116.11 (tarball Tue Feb 4 21:20:35 UTC 2020)

How are you starting the user mode instance? Can you take a screen shot of that error?
Also try doing:
$ ps ax | grep -i duplicati
I have made a search (case-insensitive) that showed no processes with duplicati, exe or mono in their name.
This info I already gave. I use the command duplicati and it says
That error does not appear in Duplicati source, nor does Google report it as a common browser error.
makes me wonder if duplicati-client (which you’ve written about a few times, so maybe use) said that.
Can you get anything up using a full path, perhaps
/usr/bin/duplicati? How do you usually start?
My bad. Most embarrasingly. I had trouble with a memory-hoggin app, and decided to disable its launch at reboot. Accidentally, I disabled Duplicati instead. I never know why.
Anyway, this morning the whole machine decided to quit working (almost) altogether. I have a new laptop that I have been preparing for use, but had hoped I could install on it the next LTS version of Ubuntu that will be published this week. Now I have to prepare a temporary setup. This will be the first time I have to do a restore in catastrophe situation, without access to he old system. I am hopeful though.
Presumably mono will finally be new enough. Ubuntu 19.10 shipped 18.104.22.168+dfsg-3.
The mono project offers 6.8.0 Stable (22.214.171.124) but all Duplicati 126.96.36.199 needs is >= v5.
