This works for me:

[https://github.com/discourse/discourse/pull/26521](https://github.com/discourse/discourse/pull/26521)

But there are several other ways to fix this to choose from:

- add env setting `USER=discourse` to the docker boot image

- add `-e USER=discourse \` to `d\exec`

- add this to `backup_restore.rb`

In addition, there is a new problem when executing `d/discourse` in the docker dev environment:

```shell
$ d/discourse backup
<internal:/usr/local/lib/ruby/site_ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:86:in `require': cannot load such file -- thor (LoadError)
        from <internal:/usr/local/lib/ruby/site_ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:86:in `require'
        from script/discourse:4:in `<main>'

```

while `d/bundle exec script/discourse backup` works (see [patch](https://github.com/discourse/discourse/compare/main...thoka:discourse:fix-backup-on-dev-install2)).
