wic shells out to a number of host-side tools to do its work: parted, mkdosfs, mcopy, the mkfs.* family, sfdisk, e2fsck, resize2fs, debugfs, blkid and more, depending on the operation and on the partition types in the image.
None of these are declared as dependencies of wic. For the bitbake do_image_wic task this is handled by the wic-tools recipe, which builds the tools into a native sysroot. Wherever else wic is installed as a package it gets none of them, and its offline lookup (wic ls/cp/write) resolves each tool over a search path that falls back to the host PATH, so on a machine that happens to have the tool installed system-wide wic succeeds while on a machine without it wic fails: wic.WicError: Can't find executable 'mcopy' Falling back to the host is unreliable even when the tool is found: wic depends on specific minimum versions of some of these tools, and an arbitrary host copy may be too old, so wic can pick up a tool that does not behave as it needs. Providing the tools as proper dependencies pins known-good versions rather than leaving it to whatever the host has. Add the tools as RDEPENDS so they are installed alongside wic and found regardless of the host. They are added to the nativesdk variant only, which is where wic is packaged for use outside a bitbake build; the native and target variants are unaffected (and wic is not expected on a target). resize2fs is named explicitly: e2fsprogs splits it into its own e2fsprogs-resize2fs package, so nativesdk-e2fsprogs alone does not provide it, and it is needed by the wic cp/write resize path. syslinux (with its isohybrid helper) is gated to x86 hosts; cdrtools (mkisofs) is native-only with no nativesdk variant and is only needed for ISO images, so it cannot be included here.
