Also: since 6.0-lts has another 3 years of support to run, is there a corresponding list of minimum requirements? I don’t find it in the 6.0 announcement, and the incus requirements page has been updated with 7.0 requirements (although it doesn’t say this explicitly)
Hmm, git is your friend… minimum kernel for 6.0 LTS is 5.4. It was bumped to 5.15 on Feb 21 2025 for incus 6.10, although not explicitly called out in the announcement apart from a line in the detailed changelog. This was still compatible with Ubuntu 22.04, which has 5.15.0 as its base (non-HWE) kernel; I’ve been running 6.23 stable on 22.04 without problems.
