ERROR SetConfig not supported by this version of Juju not supported

[Haw Loeung]

Hi,

I currently have juju installed via snaps and using the latest/candidate channel. The snap client automatically updated this morning to 2.9-rc1-groovy-amd64 and unfortunately, now I can't update configs:

| $ juju config apt-stresstest stresstest-mirror-config=@fdafsf
| {} ERROR SetConfig not supported by this version of Juju not supported

| $ juju config apt-stresstest stresstest-mirror-config=test
| {}
| ERROR SetConfig not supported by this version of Juju not supported

| $ juju config apt-stresstest stresstest-mirror-config
|
| $

Model is Juju 2.8.3 deployed in Canonistack:

| $ jsft apt-stresstest
| Model Controller Cloud/Region Version SLA Timestamp

Downgrading the 2.8.6 from latest/stable works:

| $ cat fdafsf
| - ap-northeast-1.ec2.archive.ubuntu.com: 54.248.192.197
| - ap-northeast-1.ec2.archive.ubuntu.com: 54.168.29.123
| $ juju config apt-stresstest stresstest-mirror-config=@fdafsf

| $ juju version
| 2.8.6-groovy-amd64

| $ juju config apt-stresstest stresstest-mirror-config='
| - ap-northeast-1.ec2.archive.ubuntu.com: 54.248.192.197
| - ap-northeast-1.ec2.archive.ubuntu.com: 54.168.29.123
| '
| $

Is that due to commit 2137f5518223d867379a183694ff4e16c8ec4ba4?

+// SetConfig sets configuration options on an application and the charm.

Fix committed in 2.9-rc2 can be considered released by now.
