I am getting an error while updating as a root. After Update log below error was shown in terminal.
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
I followed this answer and executed sudo apt install appstream/xenial-backports
.
My appstream
package is already updated:-
$ appstreamcli --version
AppStream CLI tool version: 0.10.6
After, force refreshing the cache data. I am getting the following error:-
$ sudo appstreamcli refresh --force
