Microk8s: Unable to install last version (492)

[franxois]

Hello, I'm unable to install last stable version of microk8s on my ubuntu 18.10.
The installation process finish with :

Error Loading request extension section req_ext
140600890205248:error:220A4076:X509 V3 routines:a2i_GENERAL_NAME:bad ip address:../crypto/x509v3/v3_alt.c:457:value=adr:192.168.1.19

I allready had microk8s but I was unable to upgrade from microk8s 1.14 (483) to 492. snap refresh was giving me the same error. I decided to remove and reinstall mikrok8s stable but I had the same error.

Using channel 1.13/stable is working.

Hi @franxois

During deployment we try to identify the machine's IP so we can issue the right certificates. The IP discovery is done by these two lines of code: https://github.com/ubuntu/microk8s/blob/master/microk8s-resources/actions/common/utils.sh#L97 and the certificate issue is here: https://github.com/ubuntu/microk8s/blob/master/microk8s-resources/actions/common/utils.sh#L117

Could you please share the output of netstat -rn and ifconfig?

Thanks

@franxois , @diegolakatos , from the output you shared it seems we are able to extract the IP correctly. Can you please show me the output of which openssl and openssl version? Is there anything special with the openssl in your system? Could you also attach the tarball of microk8s.inspect?

Same problem here with Ubuntu 18.04 while instaling the latest stable version (492). Using the previous release v1.13 solves the problem for me for now...:

sudo snap install microk8s --channel=1.13/stable --classic

@diegolakatos @stucki @franxois a fix just landed on edge. Would you please give it a try with:

sudo snap install microk8s --edge --classic

Please, let me know if this works for you so we can release it to the rest of the channels. Thanks

[diegolakatos]

@ktsakalozos it worked for me.

Thanks

[franxois]

It's ok also here :) Many thanks !

[stucki]

@ktsakalozos Works for me as well. Thank you!

[SkyNetDZ]

@ktsakalozos Thanks you

Closing this as the fix is released.
