Unclear Which home config folder was added to the write-blocked list is not stated.
What
The sandbox is the protected space Claude Code can run commands in, with limits on what those commands may touch. Two parts of its setup changed:
- Write-blocked folders: one more config folder in your home directory is now on the list commands in the sandbox may not write to.
- Java certificate script: Claude Code checks
/var/lib/dpkg/info/ca-certificates-java.postinstagainst known fingerprints, and now accepts two sets of them instead of one.
Why
This affects how the sandbox is set up, most of all on Debian-family Linux systems where that certificate script lives.
