Cucumber Linux 1.1 Release Candidate 1 is now Available

The first release candidate for Cucumber Linux 1.1 has arrived. Being a release candidate, this version has the potential to become the official 1.1 release if no critical bugs are found in it. If you find any last minute bugs, make sure to get the reports in quickly.

Starting with this release, we will no longer be providing MD5 checksums of the installation ISOs. We are doing this to encourage people to switch to using the more secure SHA256 or PGP signatures to verify the integrity of the images, since it is well known that MD5 is broken.

As always, you can get the installable ISOs at the download page and the full list of changes can be found in the CHANGELOG.

Click here for Important Information Regarding the Meltdown and Spectre Vulnerabilities (CVE-2017-5754, CVE-2017-5753 & CVE-2017-5715)

The Meltdown vulnerability has been fixed in the Linux kernel packages version 4.9.75. This update is known to break certain systems and setups, and may require manual intervention. We apologize for any inconvenience this may cause, and would not do this if this vulnerability was not extremely critical. Ths Spectre vulnerabilities were originally addressed and mitigated against in version 4.9.77 of the Linux kernel. The Spectre 2 vulnerability (CVE-2017-5715) was futher mitigated against in versions 4.9.79 and 4.9.81 of the Linux kernel. These patches are known to cause a drop in system performance. While this can reportedly this can be up to a 30% decrease in speed, some systems will experience a greater drop than others; not all systems will experience this drastic a of drop. Details about these vulnerabilities and what to do can be found on our security tracker at and our security mailing list at

Cucumber Linux 1.1 Beta 2 is now Available

The second beta for Cucumber Linux 1.1 is here, and sooner than expected. Originally, it was planned that this second beta would be released at the beginning of December; however, a critical bug was discovered in the first beta: when a user tried to update his Cucumber Linux 1.1 Beta system using Pickle, Pickle would instead attempt to downgrade the system to Cucumber Linux 1.0. For this reason, we are encouraging all users of the first beta to either completely reinstall using this second beta or follow steps 2 and 3 (but NOT step 1) of the "Upgrading to the Cucumber Linux 1.1 Alpha" instructions on this blog post.

You can go get the installable ISOs at the download page, and of course the full list of changes can be found in the CHANGELOG.

There will also be a third beta released at the beginning of December (when the second beta was originally going to be released). This will encompass what was originally going to be in second beta as outlined here.

Happy Thanksgiving!
