14 DAY TRIAL // Microsoft has recently acknowledged a new bug in the cumulative update it pushed this Patch Tuesday to Windows 10 version 1803 (April 2018 Update).
The cumulative update in question, listed as KB4489868, was published on March 12 as part of the Patch Tuesday cycle in order to correct a bunch of security vulnerabilities and introduce a fix for the infamous error 1309 encountered when installing or uninstall MSI and MSP files.
The known issues section of the original KB article included only two different entries at first, but Microsoft has recently updated it to reveal that users running the Windows Subsystem for Linux on their devices may experience a different glitch after installing this cumulative update.
Specifically, the software giant explains the following in the updated article:
“After applying this update, a stop error occurs when attempting to start the Secure Shell (SSH) client program from Windows Subsystem for Linux (WSL) with agent forwarding enabled using a command line switch (ssh –A) or a configuration setting.”
Same bug in the Fall Creators Update patch
While the company explains that it’s already working on a resolution, the fix would only be provided to users in an upcoming release. No specifics were provided, but I’m guessing the company is looking at the April Patch Tuesday cycle as the possible release target, despite new cumulative updates with non-security fixes are expected later this month.
In the meantime, users who can’t live without this feature are provided with a small workaround which Microsoft says temporarily resolves the problem:
“Disable forwarding of the authentication agent connection using a command line switch (ssh –a) or a configuration setting.”
Microsoft explains that the same bug also exists in Windows 10 cumulative update KB4489886 for the Fall Creators Update (version 1709), but the October 2018 Update (version 1809) doesn’t seem to be affected.
