Known issues
|
||||
------------
|
||||
|
||||
* Installation image does not fit on DVD, requires either DVD DL, or USB stick (5GB or more)
|
||||
* On some laptops (for example Librem 15v2), touchpad do not work directly after installation. Reboot the system to fix the issue.
|
||||
|
||||
* Windows Tools: `qvm-block` does not work
|
||||
* List of USB devices may contain device identifiers instead of name
|
||||
|
||||
* Some icons in the Qubes Manager application might not be drawn correctly when using the Xfce4 environment in Dom0. If this bothers you, please use the KDE environment instead.
|
||||
|
||||
* For other known issues take a look at [our tickets](https://github.com/QubesOS/qubes-issues/issues?q=is%3Aopen+is%3Aissue+milestone%3A%22Release+3.2%22+label%3Abug)

Upgrading
|
||||
---------
|
||||
|
||||
### From R3.1
|
||||
There is no in-place upgrade path from earlier Qubes versions. The only
|
||||
supported option to upgrade to Qubes R4.0 is to install it from scratch and use
|
||||
[qubes backup and restore tools][backup] for migrating of all of the user VMs.
|
||||
|
||||
The easiest and safest way to upgrade to Qubes R3.2 is to install it from
|
||||
scratch and use [qubes backup and restore tools](https://www.qubes-os.org/doc/backup-restore/) for
|
||||
migrating of all of the user VMs.
|
||||
|
||||
Users of Qubes R3.1 can also upgrade using [this
|
||||
procedure](https://www.qubes-os.org/doc/upgrade-to-r3.2/).

### From R3.0 or earlier
|
||||
|
||||
When upgrading from earlier versions the easiest and safest way is to install
|
