ru.archieve.ubuntu.com

where it is used as uri by

old.releases.ubuntu.com ) , but stably receiving the same after running

sudo ./zesty --mode=server --frontend=DistUpgradeViewText



  Error during update

    17.04 Zesty is also end of life. – pomsky Apr 21 '18 at 18:49
  • You should upgrade to 17.10 (artful) which is currently supported. – N0rbert Apr 21 '18 at 18:53
  • But how ? I read that the only way is to upgrade to 17.04 and only then to 17.10. Could you give any reference? – Mikhail Yudaev Apr 21 '18 at 19:09
  • You can try brute force method as described in askubuntu.com/a/361490/66509 . You can upgrade directly to bionic (18.04 LTS, will be released in 5 days), I hope. But be careful. Disable all PPAs before proceeding. – N0rbert Apr 21 '18 at 20:19
