cisco anyconnect failed due to /etc/resolv.conf settings

[Error: ]

Cisco anyconnect failed:

failed anytime at the final step.

[root cause:]

the root cause is the xattr setting on /etc/resolv.conf
I was using pppoe connection last days, and setting /etc/resolv.conf with a fixed value.

cisco anyconnect will try anyway to replace/update items in /etc/resolv.conf. failed if no update permission.

I used “chattr +i ” to keep the file stable, but it failed to update and cisco anyconnect will give up connection at last.

[solution]

chattr -i /etc/resolv.conf
