I tried Qubes OS and found out that it is too heavy and complicated for me. So I tried to install Debian from a flashed USB. However, the installer gives the following error:
the logical volume vm-sys-net-private on qubes_dom0 could not be deleted
I have a Bodhi Linux installer on another flashed USB and that gives the same error. Asking about this on the Qubes OS forum resulted in an answer suggesting the use of
"dd if=/dev/zero of=/dev/sda bs=1M or something"
I've been reading abouf the dd command and it seems to be a legit way of wiping out contents of a hard drive. lsblk gives the following output:
user@personal:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
xvda 202:0 1 20G 0 disk
├─xvda1 202:1 1 200M 0 part
├─xvda2 202:2 1 2M 0 part
└─xvda3 202:3 1 19.8G 0 part /
xvdb 202:16 1 2G 0 disk /var/spool/cron

└─xvdc3 202:35 1 9G 0 part
xvdd 202:48 1 510.7M 1 disk
How should I wirte the dd command in order to succeed with the installer? If I wipe out everything, does the computer boot from the USB?
lsblkoutput gives the impression you’re trying to install a new distribution inside the existing Qubes dom0 (see the Xen wiki). This would be similar to re-installing a different operating system in a guest VM — it’s usually simpler to delete the obsolete VM and create a new one. However I get the impression that what you really want to do is erase Qubes entirely. How are you booting the USB keys?lsblkis printed from Qubes after starting up normally instead of the USB.
