It also looks like on 24.04, the if-up.d scripts aren't run at all when resuming from sleep.
Before 24.04: - Boot - My if-up.d script that triggers for "IFACE=wlp0s20f3" gets properly triggered (it adds an IP alias to this interface using "ip addr add"). - Put ubuntu to sleep - Resume ubuntu - My if-up.d script that triggers for "IFACE=wlp0s20f3" gets properly triggered. After 24.04: - Boot - My if-up.d script that triggers for "IFACE=wlp0s20f3" gets properly triggered (it adds an IP alias to this interface using "ip addr add"). Apparently I could fix this by triggering this script with "IFACE=-all". For now I manually run the "ip addr add" command. - Put ubuntu to sleep - Resume ubuntu - My if-up.d script that triggers for "IFACE=wlp0s20f3" is not called (not even with "IFACE=-all"). The IP alias disappeared, so the interface did go down and get back up, but the script wasn't called at all. For this I don't think I have a fix? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ifupdown in Ubuntu. https://bugs.launchpad.net/bugs/2064093 Title: if-up.d files do not have effect on ubuntu 24.04 LTS Status in ifupdown package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Some time ago I wrote a detailed answer to fix an error for lowering MTU size for a cisco-compatible VPN (here:https://unix.stackexchange.com/questions/768757/unable-to-ssh- into-remote-machine-but-able-to-ping-vpnc/768758#768758) After upgrading to Ubuntu 24.04 LTS, I'm unable with the same steps to lower the MTU size. In particular, if I run the following command from the terminal sudo ifconfig your_tunnel_name mtu 1370 up it seems to lower the MTU size. However, the script under /etc/network/if-up.d is not automatically triggered. Does something change with the newer Ubuntu version?
