Hello when opening my old v1 project i got this:

 ![image](https://global.discourse-cdn.com/free1/uploads/librepcb1/original/1X/8e1fd77e670d9e55dfcbe82f8c925a1c78917de7.png)

However clicking the “Show Messages” shows the “thinking” mouse pointer icon for a couple of seconds, and then nothing. What is supposed to happen here? Can I see the messages somewhere else?

The button should open the log in a web browser, it seems this is not working on your system. Could you post the system details from the “About LibrePCB” panel here?

And do you have a custom browser command configured in the workspace settings?

Anyway it seems that we should provide some fallback solution for the case that the browser doesn’t open…

As a workaround for now, I see two options:

- Look in your temporary system folder for a librepcb folder with a migration.html inside
- Save your project to disk (possibly create a backup before, to be able to revert). Then the migration log will be saved in the project “logs” directory.

@Tubbles is it possible that you installed LibrePCB either as a Snap or as a Flatpak? That would explain why it doesn’t work - the /tmp directory is sandboxed and the stored \*.html cannot be accessed from an external web browser then. I already have a solution for it, but it would be good to have a confirmation that this was the problem.

@ubruhin Yes its installed via snap, so that’s almost certainly it!

```auto
LibrePCB Version: 2.1.0
Git Revision: af57cc985 (2026-05-19)
Qt Version: 6.4.2 (built against 6.4.2)
Operating System: Ubuntu Core 24 (x86_64)
System Locale: en_US (en-US, en-Latn-US)
Platform Plugin: xcb
TLS Library: OpenSSL 3.0.13 30 Jan 2024
OCC Library: OCCT 7.9.1
Runtime: Snap

```

No custom browser command. I only have directories in tmp:

```auto
$ snap run --shell librepcb
tubbles@thinktop25b:/home/tubbles$ find /tmp
/tmp
/tmp/librepcb
/tmp/.snap
/tmp/.snap/usr
/tmp/.snap/usr/lib
/tmp/.X11-unix
/tmp/.X11-unix/X0

```

I was able to see the messages after saving the project! Thanks 😁

Perfect, thanks for confirming 👍 I will fix that in the next release.
