Installed, but cannot run on Ubuntu 18.04

gitowiec commented 3 years ago

I am using Ubuntu Budgie 18.04

I followed the steps from README.MD

Here is the error what I see in console:

user@inspiron:~/programs/snapper-gui (master %=)$ snapper-gui 
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

I am regular user, I now a little about Python, how can I fix/debug this issue? Best regards

I think this error basically means that your snapperd daemon is not running. Or is failing to start when requested.

I don't know about Ubuntu 18.04, but on modern Debian Bullseye and Debian Unstable, the service will be auto-started when someone makes a request over DBus.

What does the below command output give you ?

rrs@priyasi:.../snapper$ snapper get-config

A properly set snapper will give you outputs like:

Hi, thanks for the help. I tested snapper-gui and it runs without problems. Maybe it was the thing You said about snapperd and it got resolved after reboot. After I run snapper-gui I saw that not nowing anything about snapper does not help me. And I got another issue, missing snapper configuration for root... Thanks for the help, closing.

ricardomv / snapper-gui

Installed, but cannot run on Ubuntu 18.04 #44
