    I found that on my Fedora installation the basesystem package was updated between Fedora 25 and 26 so that might not be a reliable way to determine the original installation time.

    There are much better ways. The simplest for most installations is to check where / is mounted and then do

    dumpe2fs /dev/whatever |grep created

    That will give you the date the filesystem itself was created

    not reliable, it shows all the same date in rpm on may Azure VMs… probably Azure installes all from the same image

    On Ubuntu Systems you could use the date of “/var/log/installer/syslog”
