Comment 1 Marcus Meissner 2018-08-28 06:03:17 UTC
is this i586??
Comment 2 Deleted Name 2018-08-28 09:05:53 UTC
It is a 32 bit CPU. I am not sure if it can be classified as i586 in particular. Could you please have a look at the attached /proc/cpuinfo and tell me if you need any other info?

Are you using kernel-default instead of kernel-pae for some reason?

Your /proc/cpuinfo shows that your CPU supports PAE.

Looks like so.
