[Solved] Error installing packages from ALA in "chrooted" environment

cmmps · 2017-12-06 13:05:20

Hello!

I'm creating a "chroot" environment with "mkarchroot" to install an older snapshot of Arch Linux (from ALA) and gcc.
It happens that the newer versions of gcc are giving me errors during compilation of a big and old project, so I decided to create this isolated build environment to compile with an older gcc version.

But after installing and downgrading the packages, within the chrooted environment, I'm no longer able to install more packages there! The file /etc/ssl/certs/ca-certificates.crt is missing!

Here are the steps I followed:

# mkarchroot /mnt/chroot base

# echo 'Server = https://archive.archlinux.org/repos/2016/12/31/$repo/os/$arch' > mnt/chroot/etc/pacman.d/mirrorlist

# arch-chroot mnt/chroot /bin/bash

# pacman -Rncs linux linux-firmware systemd

# pacman -Syyuu

# pacman -S mercurial unzip wget cpio

Packages (5) python2-2.7.13-1  cpio-2.12-3  mercurial-4.0.1-1  unzip-6.0-12  wget-1.18-3

Any suggestions?

Maybe pacman.conf/SigLevel=Never.

There was a change in the ca-sertificates in the March 2017 update. How old is the snap shot?

Thank you all.

Maybe pacman.conf/SigLevel=Never.

Didn't work...

There was a change in the ca-sertificates in the March 2017 update. How old is the snap shot?

Aaaaah... Yes, I remember that! Damn it... 2016/12/31... About one year old.
Is there any workaround? I could try a more recent snapshot and then downgrade other packages... But I first tried with even an older snapshot to avoid downgrading packages after having the snapshot.

Regards.

This is an xy problem (http://mywiki.wooledge.org/XyProblem)

Using a build env from a year ago is the wrong way to go about this. If it doesn't build with newer gcc, use a different gcc package. gcc6 is in Community, and gcc5 is in the AUR.

Hum... I didn't know that there was a gcc6. It may work. I know the the best way to compile without problems is by using version 4.8 but I know that some of my colleagues were able to compile with version 6 and 5 as well.
It would be better, indeed. Thanks!
I'm going to try it.

Yes! It works! Installing gcc6 and replacing gcc to gcc-6 and g++ to g++-6 solved my problem!
Thanks a lot.

Regarding the chroot environment, is now clear that installing any snapshot dated before March 2017 and the ca certificates changes will break pacman.

Marking as solved.

Thank you all.
