[SOLVED] sudo pacman -Syu errors

flip · 2010-11-23 14:42:45

Hi everyone!

First post here

I'm having trouble using pacman with sudo.

If I login as root and do

# pacman -Syu

it works as expected, no problems at all.

If I try it with my user account and sudo, it doesn't work, it seems the mirrors are not found and I don't know why.

$ sudo pacman -Syu
:: Synchronizing package databases...
error: failed retrieving file 'core.db.tar.gz' from ftp-stud.hs-esslingen.de : No address record
error: failed to update core (No address record)
error: failed retrieving file 'extra.db.tar.gz' from ftp-stud.hs-esslingen.de : No address record
error: failed to update extra (No address record)
error: failed retrieving file 'community.db.tar.gz' from ftp-stud.hs-esslingen.de : No address record
error: failed to update community (No address record)
error: failed to synchronize any databases

Entry from sudoers file:

flip arch=NOPASSWD: /sbin/shutdown, PASSWD: /usr/bin/pacman

I also tried:

flip ALL=(ALL) ALL

But it makes no difference.

I think I am missing something obvious here. Any ideas?

Cheers!
flip

Hi, welcome

Check your internet connection.

This is not a problem with sudo, as the pacman command would not run at all otherwise. This is either a problem with your internet connection, or the mirror. If your connection is fine then change your mirror (/etc/pacman.d/mirrorlist).

I can connect to the internet as normal user and as root.

I am behind a proxy though, maybe that is part of the problem? Proxy environment variables are correctly set in .bash_profile for user and root account.

Read "man sudoers".... Hints:

    Defaults !env_reset

or

    Defaults env_keep+="HTTP_PROXY"

Thanks!

I just found this thread:

https://bbs.archlinux.org/viewtopic.php?pid=747535

And solved it by putting this in sudoers:

Defaults env_keep += "HTTP_PROXY HTTPS_PROXY FTP_PROXY"

Everything works fine now, thanks!

Wow. This is why I never install sudo

sudo () {
su -c "$*"
}

I use it to pop up a shell with "pacman -Syu" on X startup, so i don't forget to keep my packages up to date, and to be able to just click something to shutdown/reboot. It's quite handy for that

Hey, your approach is actually nice, I think about not using sudo for updating packages anymore. But if you don't want to type in a password, for shutdown, for example, you still have to use sudo.

Well actually, there is a way to either shutdown OR reboot without a password (but not both).

The way I do it is put this in ~/.bashrc (or ~/.xinitrc)

setxkbmap -option  terminate:ctrl_alt_bksp

And then edit the line in /etc/inittab to this:

ca::ctrlaltdel:/sbin/shutdown -t3 -h now

Now, I can control-alt-backspace to quit X server and then control-alt-delete to shutdown...all without a password

please be so kind as to explain:
- what this function (?) does?
- Where do I save it?
- How do I use it?
thanks

Put this somewhere in ~/.bashrc and source it (source ~/.bashrc).

It allows commands to be run as root, without staying logged in as root.

For example:

$ sudo pacman -Syu

This will then prompt for root password and run the command, returning back to the regular user after the command has finished.

You can rename it to anything you like. I just called it sudo because it's my version of sudo. Although you can do the same with:

$ su -c "pacman -Syu"

But that's longer to type

Allan · 2010-11-23 23:16:09

Although, using that you have to type your password every time...

True, but I have nimble pianist fingers
