I just installed and it gives this error. I also formatted 10 minutes ago because I had this error and made

20 gb to /
20 gb to /home
4 gb to /swap but I cant solve this problem. Why do I have this error?

I am a programmer and i install programs like inteljidea, jdk,jre.So, should I change size of things? I have 500 GB HDD so i can give more space.

  • Looks like you are still running the installer system (with a copy-on-write root file system, as it seems), not your installed system. Maybe time to reboot, without the installation media?

  • Ah, and /dev/sr0 is a DVD-/CD-ROM drive or similar. The media in there always has 100% used, as it is read-only, too.

I was the one asking the question. I restarted and now i am on my ubuntu that was i prepared while installing. As Dubu said , i did not realize but i was on dvd ubuntu so my user name was ubuntu. I should have understood from that username because mine was not that. As i forgot my password and i thought , after restart i could see this page with my user logged, i now registred new account to answer. Thank you Dubu.

  • Thanks for posting an answer. I will close this question since because it was based on a misunderstanding it is unlikely to help anyone else. Also, please see here for how to merge your accounts.
