You are about to upgrade to a version of Ubuntu that is no longer supported.
This release of Ubuntu is no longer supported by Canonical. The support timeframe is between 9 months and 5 years after the initial release. You will not receive security updates or critical bugfixes. See https://ubuntu.com/releaseendoflife for details.
It is still possible to upgrade this version and eventually you will be able to upgrade to a supported release of Ubuntu.
Alternatively you may want to consider to reinstall the machine to the latest version, for more information on this, visit: https://ubuntu.com/desktop/get-ubuntu
For pre-installed system you may want to contact the manufacturer for instructions.

Your comments, bug reports, patches and suggestions will help ensure that our next release is the best release of Ubuntu ever. If you feel that you have found a bug please read:

If you have a question, or if you think you may have found a bug but aren't sure, first try to reach out on one of the communication channels. Matrix is the go-to for instant chatting, while Discourse would be more approriate for long discussions in a more asynchronous way. Otherwise you can still join the #ubuntu IRC channel on Libera.Chat, send an email to the Ubuntu Users mailing list, or find some help on the Ubuntu forums:
