Known issues

  • DomU firewalls have completely switched to nftables. Users should add their custom rules to the custom-input and custom-forward chains. (For more information, see issues #5031 and #6062.)

  • Templates restored in 4.2 from a pre-4.2 backup continue to target their original Qubes OS release repos. If you are using fresh templates on a clean 4.2 installation, or if you performed an in-place upgrade from 4.1 to 4.2, then this does not affect you. (For more information, see issue #8701.)

Also see the full list of open bug reports affecting Qubes 4.2.

We strongly recommend updating Qubes OS immediately after installation in order to apply all available bug fixes.

Notes

  • Qubes 4.2 does not support Debian 11 templates (see supported template releases). Please upgrade your Debian templates to Debian 12.

  • Qubes 4.2.2 includes a fix for #8332: File-copy qrexec service is overly restrictive. As explained in the issue comments, a change was introduced in Qubes 4.2.0 that caused inter-qube file-copy/move actions to reject filenames containing, e.g., non-Latin characters and certain symbols. This was a backward-incompatible change that should not have been introduced in a minor release. The fix replaces the default file-copy qrexec service that exists in Qubes 4.2.0 and 4.2.1 (qubes.Filecopy) with a less restrictive file-copy qrexec service that restores the pre-4.2 behavior (qubes.Filecopy+allow-all-bytes). Users who wish to preserve the more restrictive 4.2.0 and 4.2.1 behavior can do so by modifying their RPC policy rules to use the more restrictive service. To switch a single rule to the more restrictive behavior, change * in the argument column to + (i.e., change "any argument" to "only empty"). To use the more restrictive behavior globally, add a "deny" rule for qubes.Filecopy+allow-all-bytes before all other relevant rules. For more information, see RPC policies and Qube configuration interface.
