I am trying to install xubuntu-desktop on my Ubuntu 18.04 LTS system running on Windows 10. I first met the error: tasksel: apt-get failed (100).

Following other threads I ran sudo apt update and sudo apt upgrade and while that did not change much I tried to run sudo dpkg --configure -a, giving an error related to blueman:

This thread (Installing ubuntu-mate-desktop on 16.04, blueman configure issues) suggested to comment a line in the blueman.postint file. It might be basic, but how do I do within the Ubuntu terminal? Are there any better options to fix the issue?

  • Does "Ubuntu 18.04 LTS system running on Windows 10" mean Windows Subsystem for Linux (WSL)? – steeldriver Jun 03 '21 at 13:28
  • Yes, sorry for the confusion – Jeroen Jun 03 '21 at 13:34
  • OK so that makes things quite a bit more complicated I think - AFAIK you need an external (i.e. Windows) X server (see for example Run ubuntu-desktop on WSL (Ubuntu 18.04 LTS)) - and I'm not sure the bluetooth hardware is exposed to WSL at all – steeldriver Jun 03 '21 at 14:12
  • Thank you for the suggestion, the thread you referred me to is actually exactly the thing I am trying to do, i.e. couple my ubuntu WSL to VcXsrv. If I delete the previous failed xubuntu-desktop files and try installing again ubuntu-desktop, xubuntu-desktop or ubuntu-mate-desktop I always get the same issue: Errors were encountered while processing: blueman E: Sub-process /usr/bin/dpkg returned an error code (1). The thread I referred to in my first post says that this can be improved by commenting a line, but if I open the file blueman.postint in nano or vim it appears empty. – Jeroen Jun 03 '21 at 15:15
