Details

Description:
After recent updating with networkmanager and libnm to 1.36.0-1, I cannot set up my DSL connection.
output of `nmcli connection up DSL` (`DSL` is my the DSL connection's name):
```
Error: Connection activation failed: The device could not be readied for configuration
Hint: use 'journalctl -xe NM_CONNECTION=7caf4a0b-82bd-4d54-9d1b-40d93d20fdb0 + NM_DEVICE=eno1' to get more details.
```
Downgrade both two of them to 1.34.0 solve this problem and I can set up my DSL connection again.

Additional info:
* package version(s) networkmanager: 1.36.0-1; libnm: 1.36.0-1.
* config and/or log files etc. The attached file is the output of `journalctl -xe NM_CONNECTION=7caf4a0b-82bd-4d54-9d1b-40d93d20fdb0 + NM_DEVICE=eno1`
* link to upstream bug report, if any

Steps to reproduce:
upgrade networkmanager and libnm to 1.36.0-1, restart NetworkManager.service, then connect to a SDL connection.
This task depends upon

Hi guys,

after updating the packages "networkmanager" and "libnm" from version 1.34 to version 1.36, the file "resolv.conf" is empty.
Here the "resolv.conf" file created on my PC:
"
# Generated by NetworkManager
search --
"

Downgrading both the packages to version 1.34 does fix the issue.

Please file this upstream.

OK.

The upstream issue that I opened: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/940. Welcome to add your detail description there.

Upstream issue for above mentioned MR !1148:
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/954

The MR commits have already been cherry-picked to 'nm-1-36' branch:

Even though there's a workaround available, is this painful enough to advance the networkmanager package to the branch head?
Comment by Marcell Meszaros (MarsSeed) - Wednesday, 16 March 2022, 16:27 GMT
@heftig I don't have the expertise to decide that.
Though you could try selective patching (cherry-picking the commits directly).

I am unaffected by the issue as I don't use DSL/PPPoE.

I can only verify that on Manjaro unstable branch,
using @philm's patched rebuild networkmanager-1.36.2-1.0-x86_64
works as well as the latest Arch binary for non-DSL, non-PPPoE usage.

@philm could you please post a link to your PKGBUILD
for Manjaro's networkmanager-1.36.2-1.0-x86_64?

It seems I can't find that package version's source on the interwebs. :)

@heftig there don't seem to be too many changes yet on 'nm-1-36' branch head.

There are a few other hotfixes that might even be useful.

Comparison between release tag '1.36.2' and current branch head of 'nm-1-36':

I added not much to the PKGBUILD, just the MR. However going to head of nm-1-36 would makes sense as it will be included in 1.36.4 at some point anyway ...
