When running sudo apt update I receive this error - Metadata files have errors: /var/cache/app-info/xmls/fwupd.xml

Asked by chris pollock on 2018-08-09

This issue started for me sometime around the middle of July this year. When initially run I'm presented with this error:

AppStream system cache was updated, but problems were found: Metadata files have errors: /var/cache/app-info/xmls/fwupd.xml
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh-cache > /dev/null; fi'
E: Sub-process returned an error code

Running again within a few minutes and the error is gone.

This is:

Having done a lot of searching with Google on this issue I found that there is a problem in line 265 of the file /var/cache/app-info/xmls/fwupd.xml. The fix appears to be to change this portion of the line from this - Firmware_SF30&SN30_Pro_V1.26.dat to this - Firmware_SF30&amp;SN30_Pro_V1.26.dat I have done that as shown below by pasting lines 250->280

Manfred Hampl (m-hampl) said : #1

I assume that in your attempt to change line 265 of /var/cache/app-info/xmls/fwupd.xml you introduced another error.

Try inserting a space character before the word "target" in that line and re-run the "appstream refresh" command.
What output do you receive now?

chris pollock (cpollock) said : #2

That did the trick Manfred and so far 'sudo apt update' is running without error.

This looks good. If you do not see any further problem with appstreamcli and updating, you should set the status of this question document to "solved".

Remark: It might be required to repeat the modification "Firmware_SF30&SN30_Pro_V1.26.dat" -> "Firmware_SF30&amp;SN30_Pro_V1.26.dat" after certain package updates, as long as the related program correction has not been published for Ubuntu xenial.

chris pollock (cpollock) said : #4

So far this morning there are no problems with running 'sudo apt update'. I'll mark this as solved and thank you for the help.

chris pollock (cpollock) said : #5

Thanks Manfred Hampl, that solved my question.

chris pollock (cpollock) said : #6

There is still an issue with this. The fix provided worked for a few days now the problem has returned:

AppStream system cache was updated, but problems were found: Metadata files have errors: /var/cache/app-info/xmls/fwupd.xml
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh-cache > /dev/null; fi'
E: Sub-process returned an error code

Also note that for some reason running 'sudo apt update' a 2nd time even several minutes apart the error had disappeared.

Line 265 of /var/cache/app-info/xmls/fwupd.xml has reverted back to what it was before I made the two changes to it:

<checksum filename="Firmware_SF30&SN30_Pro_V1.26.dat" target="content" type="sha1">3ef2bdee8aca2a45b9f53b4d4cce9722523f57f8</checksum>

Searching back through my syslog hourly snippets after I saw the above I noticed:

Aug 12 06:02:33 localhost gnome-session[3104]: (gnome-software:3306): GsPlugin-WARNING **: Failed to download https://cdn.fwupd.org/downloads/firmware.xml.gz.asc, ignoring: Cannot resolve hostname

Aug 13 06:02:07 localhost fwupd[3361]: (fwupd:3361): As-WARNING **: failed to rescan: Failed to parse /var/cache/app-info/xmls/fwupd.xml file: Error on line 265: Entity did not end with a semicolon; most likely you used an ampersand character without intending to start an entity - escape ampersand as &amp;

The file fwupd.xml was changed at
-rw-r--r-- 1 root root 275847 Aug 13 06:02 fwupd.xml

When going to the link noted above - https://cdn.fwupd.org/downloads/firmware.xml.gz.asc, all that is downloaded is the gpg signature apparently for the fwupd.xml file. Backing up to https://cdn.fwupd.org/downloads/ gives a:

403 Forbidden

So, question is how was the fwupd.xml file changed? I see nothing in my syslog that shows a new file was downloaded however it was changed at 6:02 this morning. Do I change the file again to fix it?

I'm going to tag this as 'I still need an answer' because the file has reverted back to it's original state somehow.

Best Manfred Hampl (m-hampl) said : #7

This seems to confirm what I already wrote at the end of my comment #3:

It might be required to repeat the modification "Firmware_SF30&SN30_Pro_V1.26.dat" -> "Firmware_SF30&amp;SN30_Pro_V1.26.dat" after certain package updates, as long as the related program correction has not been published for Ubuntu xenial.

I have no knowledge what exactly the package update is that reverts the contents back to the wrong version with an unescaped ampersand.

chris pollock (cpollock) said : #8

Apologies Manfred I saw that comment but I guess it didn't sink in. I'll change the file back again with the fixes. Just not sure how the file got changed back. Just another mystery I guess. I'll again mark this as solved and your comment above as 'This solved my problem'.
