How to open a text editor in qubes after installation when sys-firewall configuration failed ?

[M]

How can I open a text editor in Qubes to view logs and edit xen.cfg file ?

Can’t find any when I run true the list of applications in Qubes. And I can’t get internet access from the pc as sys-firewall failed.

Version: 4.0.3

You can usually count on vi being on any linux distribution

To trouble shoot that, you can open Qube Manager and right click on
sys-firewall, then you will see "logs" at the bottom of the dropdown
menu. if you don't find the problem in there then you might try:

dom0> sudo dmesg

or

dom0> sudo systemctl

and look for your errors.

When I write the following in the Terminal either as user or as root, I only get a lot of lines with “~” on each line...

sudo vi /boot/efi/EFI/wubes/xen.cfg

What is wrong... ?

Ups, I meant:

sudo vi /boot/efi/EFI/qubes/xen.cfg

What are your language settings?
Have you tried using a different editor?(like nano)
Or a different terminal emulator?(uxterm/xfce terminal/xterm)?

No, but I managed without edit the xen file.

Now my problem is how to connect to the internet by using a USB modem - see my other thread.
