Hello @yborzykina, thank you for your feedback, but will dist-upgrade resolve all the errors those @IgorG outlined.Hello!
We sincerely recommend to perform a dist-upgrade https://support.plesk.com/hc/en-us/articles/213410369 because Ubuntu Linux 16.04 LTS is no longer supported.
Good luck!
It is not predictable what the situation will be after the upgrade. The advice to upgrade to a supported operating system is still correct. You cannot use newer Plesk versions with outdated operating systems.Hello @yborzykina, thank you for your feedback, but will dist-upgrade resolve all the errors those @IgorG outlined.
Thank you @Peter Debik I ran sudo apt-get update && sudo apt-get upgradeIt is not predictable what the situation will be after the upgrade. The advice to upgrade to a supported operating system is still correct. You cannot use newer Plesk versions with outdated operating systems.
If you are unsure how to proceed, I recommend to spin up a new server, install the latest Plesk on it and use the free Plesk Migrator extension to migrate the old installation including websites, mail and databases to the new server.
