the added line breaks to the quoted parts really mess up the citation. Can we please try to use MUAs avoiding that, or fixing that manually?I don't know what you mean. I think this is directed at Alexander? If this is directed to me I can't change mail clients, sorry.
I think it started in Alexander’s reply (Message-ID: <10b81a727ba940889095fa4bb29d0863@xxxxxxxxxxxx>) that line breaks were added to quotes. Your only adds a long “Original Message” header.
<snip>Yes it's required for the TPM model/vendor that is used in the XPS model that Paul has. If you try to run the upgrade without clearing it the firmware will reject the upgrade.Mario, thank you for your quick reaction. […] 1. Can you reproduce this issue too?I haven't seen this, but if this is a regression I also have not run anything later than 4.15-rc1 right now.
Well as far as I understood it, it’s not a regression, and there is now just better error reporting. Did you ever get the TPM to work?
2. How do I find out, what TPM firmware version is installed?fwupd will tell you. Documentation (and code) here: https://github.com/hughsie/fwupd/tree/master/plugins/dell
Unfortuntately it’s not listed with fwupd 0.7.0-0ubuntu4.3 in Ubuntu 16.04.3 LTS installed by Dell.

3. Updating to the firmware 2.4.2 from December 17th, 2017 didn’t fix
[The date is December 12th, 2017.]
The TPM in the XPS is a discrete TPM that is treated separately from the system firmware payload. It supports both a "1.2" and a "2.0" firmware. It is independently flashed from a separate TPM payload that is distributed on LVFS.
It looks like I am out of luck with Ubuntu 16.04.3 [1]. Kind regards, Paul [1] https://github.com/hughsie/fwupd/issues/301#issuecomment-342164366
