Hi everyone, I tried to update Ghost from 3.40.5 to the latest version (3.41.3), but I encountered an error. I first ran `sudo npm install -g ghost-cli@latest` to update Ghost-CLI, then I ran `ghost update` while being in the Ghost folder as usual. And I ended up with the following: > - sudo systemctl is-active ghost\_ghost-site > ✔ Checking system Node.js version > ✔ Ensuring user is not logged in as ghost user > ✔ Checking if logged in user is directory owner > ✔ Checking current folder permissions > ✔ Checking folder permissions > ✔ Checking file permissions > ✔ Checking content folder ownership > ✔ Checking memory availability > ✔ Checking free space > ✔ Checking for available migrations > ✔ Checking for latest Ghost version > > - 🐛 Fixed default urls for checkout session - Rishabh Garg > > * * * > > View the changelogs for full details: > > - Ghost - [Comparing 3.41.2...3.41.3 · TryGhost/Ghost · GitHub](https://github.com/tryghost/ghost/compare/3.41.2...3.41.3) > - Ghost-Admin - [Comparing 3.41.2...3.41.3 · TryGhost/Admin · GitHub](https://github.com/tryghost/admin/compare/3.41.2...3.41.3) > > ✔ Fetched release notes > ✖ Downloading and updating Ghost to v3.41.3 > A ProcessError occurred. > > Message: Command failed: yarn install --no-emoji --no-progress > Usage: yarn [options] > > yarn: error: no such option: --no-emoji > > Exit code: 2 > > Debug Information: > OS: Ubuntu, v20.04.2 LTS > Node Version: v10.19.0 > Ghost Version: 3.40.5 > Ghost-CLI Version: 1.15.3 > Environment: production > Command: ‘ghost update’ > > Additional log info available in: /home/ghostuser/.ghost/logs/ghost-cli-debug-2021-02-01T20\_32\_23\_186Z.log > > Try running ghost doctor to check your system for known issues. I ran `ghost doctor`, but it did not help, it passes all tests.

I tried to look up the error online, but what I found did not help much. ---

If I uninstall yarn, I then get: > Message: spawn yarn ENOENT > Exit code: ENOENT Looking for this error code usually means not enough swap memory, but I think I have enough based on this output: > ``` > total used free shared buff/cache available > > ``` > > Mem: 1.9Gi 683Mi 537Mi 1.0Mi 765Mi 1.1Gi > Swap: 1.9Gi 0B 1.9Gi So I am not sure what the issue is. I had no problem updating Ghost prior to this time. ---

> `error: no such option: --no-emoji` That’s the pertinent error. It’s possible you had a too-old, or too-new version of `yarn` installed. Can you try re-installing `yarn` then retry and post an update to this issue?

Thanks @Kevin. I reinstalled yarn using `sudo apt-get install yarn`, and ran `ghost update` and ended up with the same output as before with the `--no-emoji` thing. The command to install yarn, also said that it installed _cmdtest_ instead of yarn. I posted an update to the issue you linked. ---

Just to close the loop here since it continued on the github page. I was running a very old version of yarn and for some reason, Ubuntu was not installing a new one. @Kevin pointed me to [this article](https://classic.yarnpkg.com/en/docs/install#debian-stable) where all the instructions to install a recent version of yarn is. I uninstalled my old version and ran the 2 commands below: ```auto curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list ``` and then ```auto sudo apt update && sudo apt install yarn ``` and finally, `ghost update` worked. Thank you for your help 🙂
