I have been trying for like a month to upgrade to anything and everything from v6.28. I’ve been getting the same error no matter what version I try to update to. I use the ghost cli on Debian 12, Linux and it always kicks back with this in the log:

Debug Information:
OS: Debian GNU/Linux, v12

Node.js v22.13.1

Exit code: 1

Please, someone tell me what I’m missing.

Give this a try:

npm install -g corepack@latest
corepack enable
corepack prepare pnpm@latest --activate

And then try ghost update again.

Thank you, Thank you, Thank you.
No idea where that came from but it worked.

Thanks, @jannis! And thanks for the report - we’ve patched and released a new version of Ghost-CLI to provide these instructions to help those with a stale corepack install.
