Git warning "templates not found" while building ROS snap from rosinstall file
问题
我正在使用 snapcraft catkin/catkin-tools 插件在 Ubuntu 18.04 上构建一个 ROS 的 Snap 包。该插件有一个选项来定义 rosinstall 文件以获取包的依赖关系。然而，构建过程失败，出现了“Permission denied (publickey)”错误：
正在安装 wstool...
初始化工作区（如果需要）...
合并 /root/parts/workspace/src/snap/local/snap.rosinstall
更新工作区...
主机 'github.com（140.82.118.3）' 的真实性无法确认。
RSA 密钥指纹是 SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx。
您确定要继续连接吗（是/否）？是
更新工作区时出错：正在克隆到 '/root/parts/workspace/src/src/catkin_simple'...
警告：未找到模板 /usr/share/git-core/templates
警告：已将 'github.com,140.82.118.3'（RSA）永久添加到已知主机列表中。
git@github.com: Permission denied (publickey)。
致命：无法从远程存储库读取。
请确保您拥有正确的访问权限
并且存储库存在。
配置错误：处理 'catkin_simple' 时出错：[catkin_simple] 将 git@github.com:catkin/catkin_simple.git 版本 None 检出到 /root/parts/workspace/src/src/catkin_simple 失败。
在我的 snap.rosinstall 文件中，我只有 catkin_simple 插件的公共部分：
- git:
local-name: catkin_simple
uri: git@github.com:catkin/catkin_simple.git
我的 snapcraft.yaml 文件中的 "parts" 部分如下：
parts:
workspace:
plugin: catkin-tools
source: .
rosinstall-files: [snap/local/snap.rosinstall]
catkin-packages: [catkin_simple]
我已经尝试了不同的方法：
- 切换到 https 导致错误：
警告：未找到模板 /usr/share/git-core/templates 致命：无法找到远程帮助程序以进行 'https'。我不明白这是为什么，因为这甚至是一个公共仓库。 - 我使用 sudo 添加了一个 SSH 密钥。
ssh -T git@github.com和sudo ssh -T git@github.com，以及一般的克隆操作都可以正常工作。 - 我检查了文件夹
/usr/share/git-core/templates是否存在，这在一些其他帖子中被标记为解决方案。
我唯一能想象的是这个 VM 中缺少某些东西，snapcraft 在开始时启动。但是，再次强调，使用 snapcraft.yaml 中的 git 作为源（没有 rosinstall）可以正常工作，这是违反直觉的。
希望有人可以在这里提供更多清晰的解释。

I'm building a ROS snap with the snapcraft catkin/catkin-tools plugin on Ubuntu 18.04. This plugin has the option to define rosinstall files to fetch package dependencies. However, the build process fails with a "Permission denied (publickey)" error:
Installing wstool...

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'github.com,140.82.118.3' (RSA) to the list of known hosts.

fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
ERROR in config: Error processing 'catkin_simple' : [catkin_simple] Checkout of git@github.com:catkin/catkin_simple.git version None into /root/parts/workspace/src/src/catkin_simple failed.
In my snap.rosinstall file I have only the public catkin_simple plugin:
- git:
local-name: catkin_simple
uri: git@github.com:catkin/catkin_simple.git
The "parts" part of my snapcraft.yaml looks as follows:
parts:
workspace:
plugin: catkin-tools
source: .
rosinstall-files: [snap/local/snap.rosinstall]
catkin-packages: [catkin_simple]
I already tried different approaches:
- Changing to https results in the error:
warning: templates not found /usr/share/git-core/templates. I don't understand this since it is even a public repo.
fatal: Unable to find remote helper for 'https' - I added a SSH key with sudo. Both
ssh -T git@github.comandsudo ssh -T git@github.com, as well as cloning in general work fine. - I checked that the folder
/usr/share/git-core/templatesexists, which was marked as a solution in some other posts.
The only thing I can imagine is that something is missing in this VM, which snapcraft is starting at the beginning. However, again, using git as a source in snapcraft.yaml (without rosinstall) works fine, which is counterintuitive.
Hope that someone can add clarity here.
