Package: src:linux Version: 5.10.24-1 Severity: important Dear Maintainer, * What led up to the situation? I used the tool debos https://github.com/go-debos/debos to create a debian image on my machine. debos uses qemu to setup an install environment for debian. After a while the process got stucked. * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action?
