Does this mean dom0 is out of space? Any ideas?

It is pretty self explanatory. You don’t have enough space in dom0. You probably tried several times and cache is full. So, clear it, or even resize dom0.

How does one go about resizing dom0 and clearing the cache?? Thanks!


Cleaning:

1-delete files from .cache into the home

rm -r /home/user/.cache/*

2-delete old logs files from

/var/log/

3-delete old journal logs (if i dont need them)

sudo rm -r /var/log/journal/*

4- run the command

sudo dnf clean all


Resizing dom0

In 4.1 dom0 size is 20GB which might not be enough for large templates. So you can permanently resize dom0

$ sudo lvresize --size 40G /dev/qubes_dom0/root
$ sudo resize2fs /dev/mapper/qubes_dom0-root

or temporarily


It’s not mandatory to set 40gigs. Set as much as you want.
