Public bug reported:
Beginning with Ubuntu 19.10 (Eoan) pre-release versions, the "lshw
-json" output appears to be invalid, and can't be parsed with either
Python's json library or the jq stand-alone command:
$ sudo lshw -json | jq .
parse error: Expected separator between values at line 25, column 8
The Python json library reports "Expecting ',' delimiter: line 25 column
8 (char 718)".
The first offending snippet looks like this:
"capabilities" : {
"smbios-2.7" : "SMBIOS version 2.7",
"dmi-2.7" : "DMI version 2.7",
"smp" : "Symmetric Multi-Processing",
"vsyscall32" : "32-bit processes"
} {
"id" : "core",
"class" : "bus",
Note the "} {" line. In pre-Eoan versions of Ubuntu, the equivalent
snippet looks like this:
"capabilities" : {
"smbios-2.7" : "SMBIOS version 2.7",
"dmi-2.7" : "DMI version 2.7",
"vsyscall32" : "32-bit processes"
},
"children" : [
{
"id" : "core",
"class" : "bus",
It looks like the new version is dropping the ', "children" : [' part.
On the offending system:
$ lsb_release -rd
