The ARM64 environment was having problems on Thursday (yesterday). AMD64, PPC64 and s390x were OK. I think the Travis team got the issue fixed. Or at least I stopped seeing the failures on Friday (today). Maybe you can restart a failed job and see if the issue is resolved. ---

@noloader I am still facing the above issue on ARM64, even after restarting the failed jobs, the issue hasn’t been resolved. Also, I am facing the issue in many different packages, apart from matplotlib the issue could be seen in python-lz4 and scipy build jobs. Please have a look: [https://travis-ci.com/github/odidev/python-lz4/jobs/311136891](https://travis-ci.com/github/odidev/python-lz4/jobs/311136891) [https://travis-ci.com/github/ossdev07/scipy/jobs/301521163](https://travis-ci.com/github/ossdev07/scipy/jobs/301521163) ```auto ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly ``` This looks like an ARM64 specific issue since not getting it on AMD64 platform, Please suggest what could be done to resolve the same. ---

@Michal Please could you have a look at the issue. ---

Confirmed that we’re still seeing this issue.

[Checking the build environment](https://travis-ci.org/github/native-api/test_travis/jobs/674435368) shows that [in ARM64 Python image, `/home/travis/.cache/pip/wheels` is erroneously owned by `root`](https://travis-ci.org/github/native-api/test_travis/jobs/674435368#L12148). So a workaround would be: ```auto sudo chown -Rv $USER:$(id -g) ~/.cache/pip/wheels ``` ---

I’ve just run into the same issue @native-api thanks for the suggested workaround, will try it UPDATE: it worked, thanks! Of course that just resulted in me running into the next issue with arm64/ppc64le/s390x support… _sigh_ ---

See also [No cache support on arm64?](https://travis-ci.community/t/5416/28) where the issue is also discussed; @BanzaiMan wanted to look into it February 20, 2020, but then nothing seems to have happened? ---

Thanks @alex @native-api for the suggestions. We are using workarounds suggested. Does anyone have idea that when can it be resolved permanently for arm64? Thanks. ---

[I’m actually having this same issue with a pyInstaller buidl](https://travis-ci.com/github/sohmc/cloudflare-ddns-py/jobs/326829429). [It was working completely fine 4 months ago](https://travis-ci.com/github/sohmc/cloudflare-ddns-py/jobs/271065592). I tried the sudo method but doesn’t seem to work as the apt-get install is causing the error. ---

> [@sohmc](#): > > I tried the sudo method but doesn’t seem to work as the apt-get install is causing the error. You can put it into `before_install` then it is run before `apt-get`; see e.g. here: [https://github.com/gap-system/gap/blob/5d2fe4aad4721b03a24dd47af239b27765c49f19/.travis.yml#L163](https://github.com/gap-system/gap/blob/5d2fe4aad4721b03a24dd47af239b27765c49f19/.travis.yml#L163) ---

Now, in ARM image, `~/.cache/pip/wheels` is missing altogether: [https://travis-ci.com/github/native-api/test\_travis/jobs/403231257#L12192-L12195](https://travis-ci.com/github/native-api/test_travis/jobs/403231257#L12192-L12195) So this issue should be fixed. ---
