Summary

Towards the end of the installation of a 4.7 Solus Plasma ISO in a gnome-boxes virtual machine the process aborted with the following error:

2025-01-30 - 21:32:18 [1]:     ERROR: Installation failed: "External command crashed." 
2025-01-30 - 21:32:18 [6]:     .. - message: "External command crashed." 
2025-01-30 - 21:32:18 [6]:     .. - details: Command <i>eopkg rmf -y budgie-desktop-branding-livecd gnome-desktop-branding-livecd mate-desktop-branding-livecd plasma-desktop-branding-livecd xfce4-desktop-branding-livecd network-manager-livecd</i> crashed.
There was no output from the command.

I think the GUI talked about a timeout error, which tracks with past bugs like this.

Looking further up seems like it might have timed-out during the "Rebuilding the FilesDB..." step of the removal process:

2025-01-30 - 21:32:18 [2]:     WARNING: Process "/bin/sh" crashed. Output so far:

The following list of packages will be removed

I suspect this might take longer than the 300 second timeout on slow systems
