Hi, I ran into this issue with salt. salt failed to determine its codename grain after a fresh boot.
In case /usr/lib/os-release sets VERSION_CODENAME or /etc/debian_version specifies only one codename, lsb-release takes the information from there. base-files 11 don't set these values (and therefore trigger this bug), but base-files 11.1 does set these values (and therefore does not trigger this bug). Once bullseye is released, base-files will be updated and trigger the bug again. This issue can be easily reproduced using mmdebstrap/bdebstrap (because mmdebstap clears the apt cache) by following the "Debian live system" example: https://github.com/bdrung/bdebstrap#debian-live-system The only difference to the example is to use `bullseye` or `unstable` as suite and to install lsb-release as additional package. ``` bdebstrap -c /usr/share/doc/bdebstrap/examples/Debian-buster-live.yaml \ -n example2 --package lsb-release --suite bullseye python3 -m http.server -b localhost --directory example2 8080 & cd example2 qemu-system-x86_64 -machine accel=kvm -m 1G -device virtio-net-pci,netdev=net0 -monitor vc \ -netdev user,id=net0,hostfwd=tcp::2222-:22,guestfwd=tcp:10.0.2.252:8080-tcp:localhost:8080,hostname=debian-live \ -kernel ./vmlinuz -initrd ./initrd.img -append "boot=live fetch=http://10.0.2.252:8080/root.squashfs quiet" ``` Then you have a running live system VM where you can ssh into: ``` ssh -oUserKnownHostsFile=/dev/null -oStrictHostKeyChecking=no -p 2222 root@localhost ``` Inside the VM you have to restore the values from base-file 11: ``` sed -i '/VERSION/d' /usr/lib/os-release sed -i 's@PRETTY_NAME=.*$@PRETTY_NAME="Debian GNU/Linux bullseye/sid"@' /usr/lib/os-release echo 'bullseye/sid' > /etc/debian_version ``` Then running lsb_release will show the issue: ``` root@debian-live:~# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux bullseye/sid Release: testing/unstable Codename: n/a ``` Running `apt update` will "solve" it: ``` root@debian-live:~# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux bullseye/sid Release: testing Codename: bullseye ``` -- Benjamin Drung Senior DevOps Engineer and Debian & Ubuntu Developer Compute Platform Operations 1&1 IONOS SE | Greifswalder Str. 207 | 10405 Berlin | Deutschland E-Mail: benjamin.dr...@ionos.com | Web: www.ionos.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Hüseyin Dogan, Dr. Martin Endreß, Claudia Frese, Henning Kettler, Arthur Mai, Matthias Steinberg, Achim Weiß Aufsichtsratsvorsitzender: Markus Kadelke Member of United Internet
