Comment 3 for bug 1926672

It just says that the initial install of my system was done with 18.10. Distro release is Ubuntu 20.04. This is my desktop system, as I wanted to confirm that the error does not only happen when installing from a removable media to another removable media, but also when installing from disk to removable media. I know that ubiquity is not intended to run from a normal desktop system, but as I said this was only for testing after having experienced the issue on several installs.

Additionally, I have just tested this with Ubuntu hirsute 21.04 (stable live iso), and I am experiencing the same issue (with ubiquity 21.04.19). I have also tested whether there is a difference if I boot into the installer directly from Grub, but it is just the same as booting into live mode first and then manually starting ubiquity.

This seems somehow dangerous, as it may break a current EFI installation. The crash directory inside install-logs-2021-05-02.0 is empty, so I cannot send you a stacktrace. I took some bad fotos of the error (in German), in case this helps.
