How much more disk space will require when Ubuntu 20.04 will be updated to 20.10? [closed]

Solution 1:

As Ubuntu 20.10 is EOL the Ubuntu release-upgrade tools won't let you upgrade to it.

(The upgrade tools will download https://changelogs.ubuntu.com/meta-release which you can view in a browser, and you'll note a Supported: 0 which will tell your system that the 20.10 release is unsupported; thus Ubuntu tools won't allow upgrade to it).

6GB maybe enough to let you upgrade; it'll depend on what & how many packages you have installed that need upgrade (ie. is your system lean or bloated..)

Once an upgrade is completed you can apt autoremove to reclaim space used during upgrade.
