Poetry hangs on arch(manjaro) with python3.9

[yairfrid]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: 5.10.59-1-MANJARO Sun Aug 15 13:11:32 UTC 2021 x86_64 GNU/Linux
• Poetry version: Poetry version 1.1.11

Issue

after running pip install poetry, tried creating a new package, but poetry seems to hang.
this also reproduces on the poetry project on the master branch

example:

➜  tmp.9guve4mRZv ls
➜  tmp.9guve4mRZv poetry new example2
Created package example2 in example2
➜  tmp.9guve4mRZv cd example2
➜  example2 ls
example2  pyproject.toml  README.rst  tests
➜  example2 poetry add requests
Creating virtualenv example2-nYkGWW6L-py3.9 in /home/yairf/.cache/pypoetry/virtualenvs

Rerunning that command had no results

But on the poetry project:

➜  poetry git:(master) poetry install

This state does not change for a while(waited 10 minutes+)
adding -vvv did not give any meaningful output

the poetry install example was fixed by disabling the experimental installer

poetry config experimental.new-installer false

although installation is very slow

possible duplication of #3352

Tried in Python 3.8.11 and 3.7.11

[mattsta]

After upgrading poetry to latest version (previous version was maybe a year old?), I'm also seeing current poetry install hanging forever on some dependency configurations, but poetry update completes fine.

$ poetry -V
Poetry version 1.1.11

[floatingpurr]

Did anybody find a solution for this? I'm stuck with a similar problem (#4855)

[wereii]

After installing and trying out poetry this started to happen to me too but with python310 (5.16.0-1-MANJARO).

Though installing a package thru pip gets stuck on accessing pypi.org for definitely longer time then normally.

EDIT:
Caused by faulty ipv6 connection, resolved by setting Ignore in IPv6 Settings in my wifi connection and reconnecting. Poetry now no longer hangs.

[neersighted]

I can't reproduce the original, and all the comments are only tangentially related. This looks like the usual suspects: IPv6/networking issues or a busted cache. Try poetry cache clear --all . and rm -rf $(poetry cache-dir)/artifacts to blow away your caches and start over if you run into a hang. The two underlying issues that could cause the corrupted caches are resolved in the upcoming 1.3 branch.

I got this today. openSuSE 15.4, python 3.10 in a VM using VMware Player and network was set to NAT. Disabled IP v6 as per https://www.suse.com/support/kb/doc/?id=000016980 and 10.2.2 of https://wiki.archlinux.org/title/IPv6
rebooted and poetry install works now.

perhaps a timeout on network connections ?

[andyantrim]

Ran into this again recently on latest arch, hung on keychain until I disabled ipv6 and restarted networking fixed it. This was a fresh installation with no cache files.

Poetry (version 1.5.1)
