Hi, i’m running Duplicati 2.0.2.10_canary_2017-10-11 on Debian 8.9.

When i’m starting the duplicati service and running the backup, it’s crashing :

● duplicati.service - Duplicati web-server

Thanks for your help, i’ve tried some things : upgrade from the latest beta to the latest canary

That sounds like a Mono error - do you know what version you have installed? (You can find it next to “MonoVersion” in Duplicati’s “About” screen.)

I can’t look inside the Duplicati “About” screen because the service is crashing just after the start. How can i do ?

Thanks

I’ve runned mono -v from terminal, here the output :

Thanks for getting that mono version, and sorry - I didn’t realize the GUI was not working either, I thought it was just the backup.

Unfortunately, I don’t work with the command line much so we may have to have somebody else chime in on debugging this issue… :frowning:

No problem, again thanks for your help, the problem was mono.
This is what i do for solve this problem :

apt remove --purge --auto-remove mono-runtime
apt-get remove mono-*
apt-get autoremove
apt-get update
apt-get -f install
apt-get install mono-devel
wget https://updates.duplicati.com/beta/duplicati_2.0.2.1-1_all.deb
dpkg -i duplicati_2.0.2.1-1_all.deb
service duplicati start

Glad you figured it out!

I hope you don’t mind, but I went ahead and flagged your post as the solution in case others run into a similar issue.
