Unexpected "Install RELEASE" launcher after installation

[Romain LOUTREL]

An unexpected "Install RELEASE" is present on my installed system after downloading and running as USB key the Ubuntu installer from https://ubuntu.com/download/desktop/thank-you?country=DE&version=18.04.2&architecture=amd64

This is not a huge problem but it is confusing...

I found the suggestion to report a bug here (https://askubuntu.com/a/338952) relevant. I will not further track this bug and you can set it as "Will not fix" if you want, since I do not plan to install once again my system (next planned: Ubuntu 20.04) and I fixed my problem (by removing ubiquity).

However, it might be interesting to double check for the current version and coming 20.04.

Just for the context:

Now I can remember, that the installation encountered problems while trying to update the bootloader:

I could not go further retrying and/or skip (it was not frozen, but clicks did not have any effect) which is why I hardly switched off my computer at this point.

It might have avoid any post installation cleanup. If this is the case, then just ignore this bug.

Status changed to 'Confirmed' because the bug affects multiple users.

Could you add /var/log/installer/ from the installed system to the bug?

[Romain LOUTREL (r-loutrel+dev)]

Sorry. I do not have such a folder

Probably uninstalled as I used:
sudo apt remove --purge ubiquity

As a fix to remove the launcher
