Undefined symbol "__libc_start1@FBSD_1.7" on pfSense Plus 23.01

I did a similar fub, because I wanted to install inxi to get extended system info. Well, I get the same result. What I found that fixed the problem was change the repo options for Freebsd back to "no" and used the following command:
pkg-static install -f pkg
This reverted my pkg back to pfSense repo version.

Can you give specifics on what 'change the repo options for Freebsd back to "no"' entails on my 23.01 installation?

I haven't done anything since the fresh installation on this SSD that I can think of that would have triggered this failure of the pkg utility.

If you look under /usr/local/etc/pkg/repos directory, you'll find 2 .conf files that control whether pfsense uses it's sources and/or whether to include Freebsd's sources. I you do a manual update for some packages when using Freebsd sources, it'll ask to update pkg to the latest Freebsd version, which will mess up your source caching I believe. Setting the repos back to no Freebsd sources and then using pkg-static install -f pkg will revert pkg back to the pfsense version and reupdate the source caching. Keep in mind, this is my best guess as to what's happening since I'm not one of the developers. Even after this, I've had issues trying to upgrade from 23.01 to 23.05

martys

@djgans Thanks for the additional info!

I checked both .conf files and each say:

FreeBSD: { enabled: no }

I then did pkg-static clean -ay ; pkg-static install -f pkg with good looking (to me) output:

No harm, but no progress either. I just hope that no part of pfSense's own upgrading processes expects to use pkg and not pkg-static at this point.

If others need to install a package without upgrading/crashing pkg, i had success by lock pkg, install needed package, unlock pkg and then disable the FreeBSD repository to avoid any future issues on pfSense:

Notice how there is no mention about FreeBSD repository (2 lines in your output). And pkg-static seems to think this 'bad' version of pkg is in the PfSense repository.

I will admit that while I know lots of other package managers very well, I know next to nothing about pkg. So I'm probably missing something obvious or reading more into the output I'm getting than I should.

stephenw10

Did you set the repo to 23.01 before doing that?

Since 23.05 was released it will have become the default and pulled in pkg from that. It's not usually an issue, the upgrade process uses pkg-static for everything for just that reason.

Now how was I to know to do that? I'm just minding my business running 23.01 and without using the System > Update GUI out comes a newer version for me to eventually choose… and something in the background seems to have chosen to spring forward the CLI's repository view to the newer version that I'm not ready for, and upgraded pkg to match.

You're saying to visit the System > Update GUI to 'drop back' was the final key to getting pkg back. This is probably one of the unwritten things about the upgrade notes warning about not upgrading packages before an upgrade.

So after dropping back the setting to 23.01 and reinstalling from pkg-1.18.4_4, all is well on my installation.

I do thank you all for responding as quickly, and completely, as you did. Here's to a healthy community of users!

stephenw10

It shouldn't matter that pkg has been updated. It's only an issue if you're using pkg at the CLI in which case you will see that error if you don't use pkg-static.

sgw

I somehow lost my active repos. Toggling back and forth between 23.01 and 23.05 doesn't help.
I wonder if I could scp some files from a working machine into the system. Or somehow fix a symlink or so.

[23.01-RELEASE][root@some.host]/root: pkg-static clean -ay ; pkg-static install -fy pkg pfSense-repo pfSense-upgrade
pkg-static: No active remote repositories configured
pkg-static: No packages available to install matching 'pfSense-repo' have been found in the repositories
pkg-static: No packages available to install matching 'pfSense-upgrade' have been found in the repositories

Unfortunately this box is in a protected environment, I can't let Netgate support in right now.

help appreciated, thanks

sgw

Some more infos:

# pkg --version
ld-elf.so.1: /usr/local/sbin/pkg: Undefined symbol "__libc_start1@FBSD_1.7"

# pkg-static install -f pkg-1.18.4_4
pkg-static: No packages available to install matching 'pkg-1.18.4_4' have been found in the repositories

According to the GUI I am on 23.01 branch ... but some repo-information seems to be lost right now.

stephenw10

Try running: pfSense-repoc-static

That should pull in repo data. Or show an error.

sgw

@stephenw10 "Command not found"

I managed to downgrade "pkg" as far as I see. And I reinstalled the repos, and somehow fixed that symlink:

ln -s /usr/local/etc/pfSense/pkg/repos/pfSense-repo-prev.conf pfSense.conf

I assume I should get things right on 23.01 at first?

Currently:

stephenw10

If you re-installed the repo pkg and it repopulated the symlink then it looks like it might not have the correct cert for the repo.

Try running pkg -d update to see the full error.

Check what cert it's using:

cat /usr/local/etc/pkg.conf

stephenw10

Oh, yeah if you added the symlink manually it probably also needs the pkg.conf updating manually. In 23.01 when set to 'Prev' it should look like:

ABI=FreeBSD:14:amd64
ALTABI=freebsd:14:x86:64
PKG_ENV {
	SSL_CA_CERT_FILE=/etc/ssl/netgate-ca.pem
	SSL_CLIENT_CERT_FILE=/usr/local/etc/pfSense/pkg/repos/pfSense-repo-prev-cert.pem
	SSL_CLIENT_KEY_FILE=/usr/local/etc/pfSense/pkg/repos/pfSense-repo-prev-key.pem
}

sgw

@stephenw10

Compared /usr/local/etc/pkg.conf with another 23.01 box.

The whole block "PKG_ENV" was missing, added it.

Yes, try switching to 23.05 and see if it allows you to update.
