LMDE XFCE can't connect to pppoe using network manager

[Igor Tarasov]

Using LMDE XFCE 201104 i386. Created new PPPoE connection, trying to connect and getting error. The log says:

Mar 25 20:22:30 mint pppd[2887]: Plugin /usr/lib/pppd/2.4.5/nm-pppd-plugin.so is for pppd version 2.4.5, this is 2.4.4
Mar 25 20:22:30 mint NetworkManager[2117]: <warn> pppd pid 2887 exited with error: pppd options error

Versions mismatch make it fail any time whatever options you use.

Ubuntu-based distros work well with PPPoE.

TiGR: Can you confirm the versions of ppp and network-manager-pptp installed on your system?

[Igor Tarasov (tarasov-igor)]

Why did you mark bug as Invalid? Here are versions:

mint@mint ~ $ apt-cache show ppp
Package: ppp
...
Architecture: i386
Version: 2.4.5-4
Depends: libc6 (>= 2.7), libpam0g (>= 0.99.7.1), libpcap0.8 (>= 0.9.8), libpam-modules, libpam-runtime, procps
Breaks: network-manager (<= 0.8.0.999-1), network-manager-pptp (<= 0.8.0.999-1), pppdcapiplugin (<= 1:3.9.20060704+dfsg.1-1)
...
mint@mint ~ $ apt-cache show network-manager-pptp
Package: network-manager-pptp
...
Architecture: i386
Version: 0.8.1-1
Depends: libc6 (>= 2.3.6-6~), libdbus-1-3 (>= 1.0.2), libdbus-glib-1-2 (>= 0.78), libglib2.0-0 (>= 2.16.0), libnm-glib-vpn1 (>= 0.7.999), libnm-glib2 (>= 0.7.999), libnm-util1 (>= 0.7.0), pptp-linux, ppp (>= 2.4.5), ppp (<< 2.4.6)

See for yourself. ppp version is 2.4.4, nm-pptp requires ppp >= 2.4.5, and network-manager packages are thus broken.

It is a live session of linuxmint-debian-201104-rc-i386.iso. I have not updated anything, since I could not connect to network.

I've copied wrong data about ppp.

There is one optional package, with version 2.4.5. It is not installed. The one that is installed is this:

Package: ppp
Status: install ok installed
Priority: optional
Section: admin
Installed-Size: 900
Maintainer: Marco d'Itri <email address hidden>
Architecture: i386
Version: 2.4.4rel-10.1
Replaces: ppp-pam, ppp-udeb
Depends: libc6 (>= 2.7-1), libpam0g (>= 0.99.7.1), libpcap0.8 (>= 0.9.3-1), libpam-modules, libpam-runtime (>= 0.76-13.1), netbase, procps

[Clement Lefebvre (clementlefebvre)]

Thanks. You simply have the wrong version of ppp, or the wrong ISO?

The correct filename for the ISO should be: linuxmint-debian-201104-xfce-rc-i386.iso
It's MD5 is: 308e3aa7a0f9763667f21b408d1af0fe
It comes with ppp version 2.4.5-5

[Igor Tarasov (tarasov-igor)]

I have this exact ISO with this exact hash. And it holds ppp 2.4.4. As I said, dpkg somehow knows about 2.4.5 package, but it is not installed.

[Clement Lefebvre (clementlefebvre)]

Hi TiGR, can you paste the content of the following commands:

"apt version ppp"

"apt show ppp"

"apt search ppp"

"cat /etc/linuxmint/info"
