I am trying to build a snap and i have used flutter for building the app. while creating the snap package i am getting an error.

Priming gnome-3-28-extension

The command 'system_information' for 'system_information' was resolved to 'bin/system_information'.
The command 'system_information' has been changed to 'bin/system_information'.

We would appreciate it if you anonymously reported this issue.
No other data than the traceback and the version of snapcraft in use will be sent.
Would you like to send this error data? (Yes/No/Always/View) [no]: no
snapcraft-system-information # 

I have tried snapcraft clean already but it didn’t cleared the issue.


Actually the error is generating from multipass which i used to build my snap packages. I tried deleting /build and building again but it didn’t worked.

I found an alternate way to build snaps using lxd
