Hi there,
yesterday I update the host and a container from Debian 13.3 to 13.5, then openfortivpn on the container stopped working.
Symptom (on the container, user admin) - Trying to launch the vpn manually I get:
$ sudo openfortivpn
INFO: Connected to gateway.
INFO: Authenticated.
INFO: Remote gateway has allocated a VPN.
Couldn't set tty to PPP discipline: Operation not permitted
ERROR: read: Input/output error
INFO: Cancelling threads...
INFO: Cleanup, joining threads...
ERROR: pppd: An immediately fatal error of some kind occurred, such as an essential system call failing, or running out of virtual memory.
INFO: Terminated pppd.
INFO: Closed connection to gateway.
INFO: Logged out.
On the container (user admin):
$ uname -a
Linux vdebmon 7.0.6-2-pve #1 SMP PREEMPT_DYNAMIC PMX 7.0.6-2 (2026-05-29T11:08Z) x86_64 GNU/Linux
$ ls -l /etc/openfortivpn/config
-rw------- 1 root root 232 Jun 6 14:54 /etc/openfortivpn/config
$ sudo cat /etc/openfortivpn/config
### configuration file for openfortivpn, see man openfortivpn(1) ###

$ sudo openfortivpn --version

On the host (user root):
$ pveversion

searchdomain: ...omissis...
swap: 4096
unprivileged: 1
lxc.mount.entry: /dev/ppp dev/ppp none bind,create=file
I guess openfortivpn itself hasn't been updated, current version was published on Feb 2025.
Has anybody any clue?
