Package: libell0 Version: 0.69-1 Severity: critical I just updated my Sid install, wifi (iwd based) was broken afterwards. Found the following in journalctl indicating that the libell0 update was responsible. Booted a recovery disc and had to downgrade both libell0 and iwd to versions from testing, rebooted again and wifi is back.
/usr/libexec/iwd: symbol lookup error: /usr/libexec/iwd: undefined symbol: l_genl_attr_next, version ELL_0.10 Second time in the past few weeks Sid has been critically broken due to such a symbol error. Perhaps we could benefit from some infrastructure that automatically checks for missing symbol issues when updated lib packages are uploaded and blocks them unless they have a suitable breaks statement.
