Arch Linux User Repository

After package installation, vpnagentd service must be enabled: sudo systemctl enable --now vpnagentd.service; sudo systemctl status vpnagentd.service

I'm actually on manjaro, so I think the issue was them still pointing to a slightly older extra repo. After manjaro update it works fine. Thanks all!

@ExpandingMan AUR helpers, like yay, should install libxml2-legacy from extra automatically, since it's listed as a dependency. If it doesn't work somehow, you can install it manually with pacman:

# pacman -Su libxml2-legacy

@JotaRata it works for me. Versions 2.13 and 2.11 are binary compatible, and have the same soname: libxml2.so.2. If it doesn't work for you, what's the error message when launching from terminal?

$ cisco-secure-client

For some reason libxml2-legacy still doesn't work, the version that is available in the repository is version 2.13 abd the one Anyconnect requires is version 2.11. One potential fix is to manually download libxml2 2.11 from the archive and install it in /usr/local/lib

For some reason I get

No AUR package found for libxml2-legacy

and then it won't install.

Clearly this exists (https://archlinux.org/packages/extra/x86_64/libxml2-legacy/) but it also doesn't seem to list this package as a dependent.

@marcin maybe some archive.org (temporary) issues. It downloads fine for me now:

I think the archive.org link does not work anymore:

curl: (7) Failed to connect to archive.org port 443 after 4 ms: Could not connect to server

Added libxml2-legacy in to depends.

Just hit the same problem, the client does not start because it requires libxml2-legacy. It would be great if you updated the PKGBUILD.

I'm having a "The certificate on the secure gateway is invalid" error. After a system update.
