I also try command fllowing your reply，the results are the same.

It's not a DNS issue. The error is Could not resolve hostname https:. It shouldn't try to resolve https:, it's a scheme, not a domain name.

Thank you very much for your reply.
I followed your command.[1]

Please wrap your stacktrace, excerpt of code, etc... with triple backquote before and after.
So this becomes more readable.
Thanks in advance.

Thank you very much for your reply.
And I follow your guidance，now，all the services are started，but when I save code in my Software Heritage platform, the status always failed, I checked log :

Thanks for opening this issue.

All repositories have been successfully processed, closing this.

awesome, thanks.

Ok so I applied the above process locally and no bad surprises when running all test suites. I will push the changes to remote then and close that task once it is done.

Ok so the plan to integrate isort in all repos will be the following:

1. Integrate the following diff (manually) in all repos using the change-all-repos script from @vlorentz but do not push to remote yet

diff --git a/.pre-commit-config.yaml b/.pre-commit-config.yaml
index 5ab0e08..df70797 100644

You might need to skip .py files in tests/*/data (eg. swh-web iirc)

(I was initially surprised by the mixing together of "import" lines with "from ... import" ones, but upon reflection it makes a lot of sense, because one might have to switch between the two forms, and it's silly to have to move the line back and forth between import blocks when that happens.)

You might need to skip .py files in tests/*/data (eg. swh-web iirc)

+1 to the idea (and to the specific config as I have already bikeshed it)

Let's consider this done for now. Still not "great" loading time, but much better than before.
