Something isn't working

Thanks for the bug, something went wrong in the last release. Fixed on mainline! |
In that case, can this be closed? I cannot reproduce the error with the following command: firejail --net=eth0 --netlock --noprofile /bin/sh -c 'sleep 70' |

closing! |

Description
Attempting to pass --netlock doesn't seem to be recognized by firejail - there is no terminal indication of it being present (as was demonstrated in the demo video for netlock's release), and I am able to access other networks that have not been connected to well after the default 1 minute timeout.
I also seem to get the following output in any command that I run which contains --netlock:
Error: no valid sandboxIt seemingly makes no difference as to which command is run, or if I include the --net option as specified as required for --netlock
It should also be noted that the error appears with a delay. For example, running
nanowill cause the error to appear inside of the text editor. Runninghtopwill cause the error to appear as new lines as the bottom of the screen. Running a command/program which has a longer startup will show up as a normal line of logs in a terminal.Steps to Reproduce
firejail --net=eth0 --netlock --noprofile *any command*firejail --netlock --noprofile *any command*firejail --netlock *any command*All of the above will still output the same error, and netlock's specific logs are not present anywhere
Expected behavior
I expected netlock to function
Actual behavior
Netlock did not function
Behavior without a profile
Profile has no bearing
Additional context
I'm just trying to limit a program to local network traffic only. This seemed like the easiest way that I could find, since I can control what this device tries to connect to within the first minute or so.

Error: invalid network filter file *filename*I've tried the default template configs as well as one that I made myself, none seem to work. Debug doesn't add any additional information or context.
