Pamac behind proxy

Support
1

Hi there all,

I’m trying to update AUR based packages through pamac. My configuration is proxy exclusive, including DNS resolutions. Retrieving the packages DB’s etc seems to work through the proxy although the “Cloning build files” step seems to be willing to engage direct communications.

Is there a way to alter these behaviors? I’ve mangled with:
/etc/pamac.conf
/etc/pacman.conf
/etc/wgetrc

These lines are present in my /etc/environment

export http_proxy=http://proxy_fqdn:8080/
export {https,ftp,rsync,dns,all}_proxy=$http_proxy 
export {HTTP,HTTPS,FTP,RSYNC,DNS,ALL}_PROXY=$http_proxy

An output from a failing attempt at pamac, I’d be interested if one’s know how that “Cloning build files” process is actually launched and if there is anything under my control to possibly alter/modify it’s behaviors:

sudo pamac update --aur

On a note here, pacman updates works all fine behind the proxy (sudo pacman -Syyuu).

Thanks a lot,

As a workaround, have you tried proxychains-ng?

Hi there,

Thanks for the proposal, I’ll test it out. Meanwhile I went a little bit further and found something that works on the downloads side:

export proxy=http://proxy_fqdn:port/
alias proxypamac='http_proxy=$proxy https_proxy=$proxy pamac update --aur --no-confirm --force-refresh'

I still don’t really get why I need to “force” the http(s)_proxy variable as its already set in the environment but well, that works mind you…

I’ll test proxychain to see if there is anything better out of that.

Thanks,
M.

Hi @mokaz,

See:

https://wiki.archlinux.org/title/Proxy_server

Some programs, such as wget and (used by pacman) CURL, use environment variables of the form protocol_proxy to determine the proxy for a given protocol (e.g. HTTP, FTP, …).

Below is an example on how to set these variables in a shell:

export http_proxy=http://10.203.0.1:5187/
export https_proxy=$http_proxy
export ftp_proxy=$http_proxy
export rsync_proxy=$http_proxy
export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

Some programs look for the all caps version of the environment variables.

Try removing “export” from the beginning of the lines in /etc/environment so it only contains KEY=VALUE lines.
The file /etc/environment is owned by PAM and supports lines having the “export” keyword to be compatible with bash syntax. But it does not look like it is supported by Systemd services (at least it is not mentioned in the documentation) and it looks like Pamac uses Systemd services for the AUR builds. See

man pam_env
man environment.d

The pamac(the “Add/Remove Ssoftware” app) can’t fetch update nor update software, if I put:

http_proxy=http://127.0.0.1:7890
https_proxy=$http_proxy
ftp_proxy=$http_proxy
rsync_proxy=$http_proxy
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

in /etc/environment.

How to make pamac work with these settings, so that I don’t have to specify these settings for every other app need proxy.

That’s how I’m doing things…

alias pamacb='http_proxy=$http_proxy https_proxy=$http_proxy pamac build'
alias pamaci='http_proxy=$http_proxy https_proxy=$http_proxy pamac install'
alias pamacr='http_proxy=$http_proxy https_proxy=$http_proxy pamac update --aur --no-confirm --force-refresh'

Update:
Looks like $http_proxy syntax can’t be recognized. You could get more information/logs about the previous error when using terminal. (Such as pamac update)

This works with no error:

http_proxy=http://127.0.0.1:7890
https_proxy=http://127.0.0.1:7890
ftp_proxy=http://127.0.0.1:7890
rsync_proxy=http://127.0.0.1:7890
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

Isn’t that last line effectively disabling the proxy?
