[23:43] <guiverc> my lunar isn't booting  :(  shim issue.  my box is dual boot; jammy & lunar; i only used jammy yesterday & it still boots, but I gather shim 15.7 update is reason that lunar fails to now boot; anyone got anywhere I can read up so I can learn more about issue & how to fix (noted shim 15.7 discussion yesterday on #ubuntu-devel ML, but I need more basic detail to learn more so I can fix it; i mostly use older hardware)
