The issue reported here is different than the CNAME issue. Basically LVFS has gotten a lot bigger and the fwupd 0.7.x release couldn't handle the size of the metadata now. Please reference this bug in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/fwupd/+bug/1829813
This workaround can be backported for it: https://github.com/hughsie/fwupd/commit/a1e6e7ff254f3409e0bced0fb400073d6e2b96e8 > -----Original Message----- > From: Xavier Bestel <[email protected]> > Sent: Monday, July 29, 2019 5:09 AM > To: [email protected] > Subject: Bug#912414: Workaround failed > > > [EXTERNAL EMAIL] > > FWIW, even changing the configuration file as described fails: > > root@gitlab:~# fwupdmgr --verbose refresh > failed to update metadata: Failed to parse XML: Mismatched XML
