Install error init.xy on CentOS 8 via proxy

[Jacques-Olivier]

Hi there,

I am on a fresh install of CentOS 8.
Everything is fine until the install script try to download init.xy.

I have the msg :

Downloading kernel, init and fog-client binaries… * Could not download init.xz properly

We use a proxy, but i have added the domain fogproject.org.
And if i use wget https://fogproject.org/inits/init.xz, it works fine.

Any idea ?

[Jacques-Olivier]

Using

bash -x installfog.sh

Show me these commands :

curl --silent -kOL https://github.com/FOGProject/fos/releases/download/1.5.9/init.xz
+ curl --silent -kOL https://github.com/FOGProject/fos/releases/download/1.5.9/init.xz.sha256
+ let cnt+=1
+ [[ 1 -ne 0 ]]
+ [[ 9 -lt 10 ]]
+ [[ -f init.xz.sha256 ]]
+ checksum=1
+ [[ 1 -ne 0 ]]
+ curl --silent -kOL https://github.com/FOGProject/fos/releases/download/1.5.9/init.xz
+ curl --silent -kOL https://github.com/FOGProject/fos/releases/download/1.5.9/init.xz.sha256
+ let cnt+=1
+ [[ 1 -ne 0 ]]
+ [[ 10 -lt 10 ]]
+ [[ 1 -ne 0 ]]
+ echo ' * Could not download init.xz properly'
* Could not download init.xz properly
+ [[ -z '' ]]
+ exit 1

@jacques-olivier Are you behind a proxy server that wget is configured for?

[Jacques-Olivier]

@tom-elliott Hi Tom, yes we are behind a Squid proxi.
We have added http://github.com and https://fogproject.org in out white list.

But the curl command line is not working in /lib/common/functions.sh

[Tom Elliott]

@jacques-olivier I’m going to guess your fog server has a file under the root’s home called .wgetrc

cat ~/.wgetrc

[Jacques-Olivier]

@tom-elliott I have :

cat .wget-hsts

# HSTS 1.0 Known Hosts database for GNU Wget.
# Edit at your own risk.
# <hostname>    <port>  <incl. subdomains>      <created>       <max-age>
fogproject.org  0       0       1606476412      15768000
github.com      0       1       1606477609      31536000

@Jacques-Olivier You need to either set proxy in .curlrc or through shell environment variables.

@Tom-Elliott curl is used for those downloads not wget.

[Tom Elliott]

@sebastian-roth I know that, but I wanted to know if there was a .wgetrc that’s allowing proxy (which would explain why wget works, but curl doesn’t)

[Tom Elliott]

@jacques-olivier Can you try the same principal for curl:

@jacques-olivier In my office we are behind a proxy server too and all I do is set the environment variables (when installing fog) and the installer works correctly. I rebuild a fog server at least once a month or testing reasons so I know it works well with both centos 8 and ubuntu 20.04

export http_proxy=http://proxy.domain.com:8080
export ftp_proxy=http://proxy.domain.com:8080
export https_proxy=http://proxy.domain.com:8080
export no_proxy="127.0.0.1,*.domain.com,192.168.50.53"

Where 192.168.50.53 is the IP address of the FOG Server.

If you want them set every time then set them in bashrc or your default profile. Once they are exported then just run the installer normally. Its a bit more complicated if your proxy server needs authentication to get onto the internet. I don’t have any personal experience. In the case of the proxy server it would be much easier to white list the FOG server IP than the domains the FOG server reaches out to for the packages.

@george1421 Thanks, i will try that.
