Mono update breaks OneDrive v2

jek · July 20, 2019, 2:02pm

I just upgraded to Mono 6.0.0 Stable (6.0.0.313) on ubuntu 18. This breaks (at least) the OneDrive v2 interface. The error message is:

“Only ‘http’ and ‘https’ schemes are allowed”

Downgrading to 5.20 solves the problem at the moment.

Same here. OneDrive v2. The Docker container (linuxserver) updated the mono packages to 6.0.0.313.

Failed: Only 'http' and 'https' schemes are allowed.

Parameter name: requestUri

Details: System.ArgumentException: Only 'http' and 'https' schemes are allowed.

Here Mono 6 fails too

HtownJay · July 31, 2019, 1:07am

I am experiencing the same issue with Mono 6 and OneDrive

warwickmm · July 31, 2019, 4:27am

It appears that we have some compatibility issues with mono 6. What versions of duplicati are you using?

jek · July 31, 2019, 7:26am

I tried it with 2.0.4.23 and 2.0.4.5 (and maybe 2.0.4.22, too)

jfabaf · July 31, 2019, 9:24am

Same issue here with linuxserver.io docker image.
Duplicati version: Duplicati - 2.0.4.23_beta_2019-07-14

Same issue here with the latest linuxserver.io docker image.

kinghat · August 3, 2019, 4:27pm

yep. updated to fix the box.com issue and not get that error for onedrivev2:

and the in the log:

xstream · August 3, 2019, 7:17pm

I can replicate this too unfortunately.

warwickmm · August 3, 2019, 11:26pm

The OneDrive backend is the only one that uses a different HTTP client, which may explain why it only affects OneDrive users. Unfortunately, I don’t have mono 6 yet to test, but there’s a slight chance that it’s a regression in mono:

ts678 · August 4, 2019, 12:49pm

If you’re willing to risk a machine (a VM might be good for test) it “looks” like it’s at mono-project.com

The latest Stable Mono release is: 6.0.0 Stable (6.0.0.313)
The latest Preview Mono release is: 6.4.0 Preview (6.4.0.150)

My Linux Mint Update Manager is offering

but because I don’t see Ubuntu offering it, I suspect it’s because I once used the mono directions, and added the mono-project repo to my apt sources, per the OS-specific directions on the download page.

ts678 · August 8, 2019, 6:08pm

Possibly less risky would be to stay on whatever 6.0.0 Stable is at, but ask mono to change URI handling:

export MONO_URI_DOTNETRELATIVEORABSOLUTE=true

then start Duplicati via the duplicati script or whatever you run…

After confirming 6.0.0.319 fails on Destination “Test connection”, I set the variable. Backup/restore works.

aaron-von-awesome · August 9, 2019, 4:22am

This suggestion worked for me as well

I am on mono 6.0.0.319 / Duplicati 2.0.4.23_beta_2019-07-14 / Linux Mint 19.2

ts678 · August 9, 2019, 2:49pm

As a side issue, Linux Mint Releases shows their only releases are LTS releases, based on Ubuntu LTS. Other distros such as KDE neon take the same approach of building on a stable base, but stability leads sometimes into difficulty of change e.g. to a newer mono version either by distro or bypass-distro efforts.

For any who were hit by this problem, did the new mono come from your distro’s default repos, or did the https://www.mono-project.com/download/stable/#download-lin addition of mono project’s repo lead you?

This ties into a question of how current the mono on an LTS distro will be, in case Duplicati needs newer.

Survey for Linux users, which version of Mono do you have installed?

xstream · August 11, 2019, 8:55am

The workaround does not work for me on Debian 9 / Mono 6.0.0.319 / Duplicati 2.0.4.23_beta_2019-07-14

I have confirmed that the variable reads back true:
printenv MONO_URI_DOTNETRELATIVEORABSOLUTE
true

I have also tried restarting the duplicati service.

ts678 · August 11, 2019, 11:12am

The essential question is – does it read back true for mono? You can probably check that with ps:

Output Modifiers
e Show the environment after the command.

The rest of the job is finding Duplicati which will find its mono, e.g. ps -ef e | grep duplicati

How to set environment variable in systemd service?

I’m not a systemd expert. If nothing from above works, there are other systemd references around.
Perhaps you could also try setting the variable globally, but systemd still has to let it go into service.

xstream · August 11, 2019, 11:32am

The essential question is – does it read back true for mono?

I assumed that if I export it as root and duplicati runs as root it would be the same but I don’t know much about environment variable scope.

How to set environment variable in systemd service?

Thanks, I used systemctl edit duplicati.service to set the environment variable there as

[Service]
Environment="MONO_URI_DOTNETRELATIVEORABSOLUTE=true"

and it works. I guess this is perfect workaround for now since it is persistent and should not impact anything but duplicati.

ts678 · August 11, 2019, 11:43am

They inherit from parent to child (repeat and repeat) unless steps are taken to stop that, so your setting would affect Duplicati and any scripts that it runs (which might not be relevant at all unless you do that).

OTOH anything else that uses the new mono won’t get it, but based on the scarcity of reports to mono, perhaps little else is affected. I do hope they change the default. They seem to for their own test code…
