I didn't add one of the required dependencies to the control file, and this package is called libgtk3-imageview-perl . When I tried packaging in Buster, this package was not in Buster, so I had to build it separately, but fortunately it was in Bullseye.------------------------------------------------------------------------------------------------------------There is a future society, but my future is not what others do.Dept. of Information Science, Graduate School, Korea National Open University2021년 8월 18일 (수) 오전 5:55, Michael Kogan <michael.kogan@gmx.net>님이 작성:I see, thanks for clarifying this! We have documented the dependencies here: https://shutter-project.org/downloads/dependencies/ Most of them are actually named in Debian/Ubuntu naming style, as far as I know.As jiho lee already mentioned, it would be necessary to package https://metacpan.org/dist/GooCanvas2-CairoTypes and add it as dependency.The dependency gir1.2-appindicator3-0.1 is necessary for core functionality (showing the tray icon) but only for Gnome users. Don't know what the best way to deal with this is... In the Ubuntu PPA this is a "Recommended" dependency, in Arch Linux an optional one.Am Di., 17.

I’m not a Perl expert) META.yml or something, or at least in the README file.--Cheers,Andrej
