I spent a lot of time installing several extensions and third-party applications from the software centre in ubuntu to customize the look and feel of the os.
Also, I have a lot of Softwares installed like PyCharm and sublime text and vscode. All of these are again customized. I can, of course, do all the customizations again, but it would consume a significant amount of time.
I wanted to know if all of these Softwares will get erased/removed after I perform the upgrade.
I'm using this command to bring up the update manager dialogue which would then prompt me to proceed with the update.
update-manager -c
Also, will this command make sure I keep all the installed Softwares even after the upgrade?
RELEASE_UPGRADER_ALLOW_THIRD_PARTY=1 update-manager -c
I will only proceed with the upgrade if I'm sure all the applications will remain intact after the upgrade, otherwise, I'm perfectly happy with using Ubuntu 18.04.
According to this answer, the already installed apps should not get damaged by the update. Does this answer still hold for 18.04 to 20.04?
