Running `cephadm bootstrap` (or any cephadm subcommand) on a fresh install fails immediately with: - Traceback (most recent call last): - File "/usr/sbin/cephadm", line 141, in <module> - from cephadmlib import runscripts - File "/usr/lib/python3/dist-packages/cephadmlib/runscripts.py", line 10, in <module> - ... - File "/usr/lib/python3/dist-packages/cephadmlib/container_types.py", line 12, in <module> - from ceph.cephadm.images import DefaultImages - ModuleNotFoundError: No module named 'ceph' + Traceback (most recent call last): + File "/usr/sbin/cephadm", line 141, in <module> + from cephadmlib import runscripts + File "/usr/lib/python3/dist-packages/cephadmlib/runscripts.py", line 10, in <module> + ... + File "/usr/lib/python3/dist-packages/cephadmlib/container_types.py", line 12, in <module> + from ceph.cephadm.images import DefaultImages + ModuleNotFoundError: No module named 'ceph' Currently declared Depends are only `lvm2 | python3` per https://packages.ubuntu.com/resolute/cephadm. Reproducer (LXD VM): - $ lxc launch --vm ubuntu:26.04 c1 - $ lxc shell c1 -- apt-get update - $ lxc shell c1 -- apt-get install -y cephadm - $ lxc shell c1 -- cephadm version - ModuleNotFoundError: No module named 'ceph' + $ lxc launch --vm ubuntu:26.04 c1 + $ lxc shell c1 -- apt-get update + $ lxc shell c1 -- apt-get install -y cephadm + $ lxc shell c1 -- cephadm version + ModuleNotFoundError: No module named 'ceph' Workaround: - apt-get install -y cephadm python3-ceph-common + apt-get install -y cephadm python3-ceph-common Expected fix: add `python3-ceph-common (>= ${binary:Version})` to cephadm's Depends in debian/control. The squid (19.x) cephadm in noble shipped as a single-file script with no Python imports beyond the stdlib, so this regression is specific to the Tentacle refactor that moved logic into cephadmlib/ and ceph/cephadm/.
