How can I determine when Ubuntu was installed in my computer? There was a different question posted here.

    What was wrong with the answers there? /var/log/installer, /boot, and dumpe2fs all look OK to me.

  • @Mikel. The reason is that they show different dates. For instance, dumpe2fs and /var/log/installer show creation date as 05.11.2010 while /boot shows as 29.01.2011. That is why I wanted to find out precise method to get this information without any doubts.

    @Bakhtiyor Then most probably something happened to /boot. When dumpe2fs and /var/log/installer point to the same answer I won't keep any doubt.

  • All right guys. So, what do you suggest me to do with the question? Just delete it or what?

    I wouldn't rely on that. For example, FreeBSD rotates /var/log/wtmp by default, so when I run last on one of my FreeBSD boxes I get "wtmp begins Thu Feb 3 09:50:42 EST 2011". My Slackware box does the same thing, I installed the OS on it years ago but last reports that wtmp began last week. I don't have an Ubuntu box handy to check.
