I went ahead and reported this on Launchpad, we’ll see if anyone there has any ideas. A new SRU (2.30) of snapd also seems to be in the works, but no release as of yet.

Since some time over the holidays I’ve had problems refreshing/installing the Wekan snap [1] on my home server and also my desktop. The installation stalls at the configuration phase, which on the surface looks a bit like bug #1674193 [2], but here core gets installed just fine, and the hang occurs just alike if I first install just core, then the `wekan` snap separately.

14.52 jani@saegusa:~$ sudo snap install wekan
[sudo] salasana henkilölle jani:
error: cannot perform the following tasks:
– Run configure hook of ”wekan” snap if present (run hook ”configure”: <exceeded maximum runtime of 5m0s>)

Installing other snaps works (the couple that I tried just to be able to say this did anyway).

I’ve reported this on the Wekan snap Github page [3], but there’s been no confirmation from anyone else affected so far. Also, I’m unable to reproduce this myself in a VM and on at least one other (physical) desktop I have access to.

So naturally I’ve looked for differences between these systems, but so far the only correlating one I’m pretty sure of is an Apparmor denial:

apparmor=”DENIED” operation=”open” profile=”snap.wekan.mongodb” name=”/sys/block/” pid=9478 comm=”mongod” requested_mask=”r” denied_mask=”r” fsuid=0 ouid=0

The two systems where Apparmor denies mongodb’s access to /sys/block get stuck at the configure hook, whereas systems that don’t deny access finish the configuration (and installation) successfully.

I have not tweaked any Apparmor configuration on any of these systems prior to this issue cropping up (not that I can remember anyway). I’ve also not touched anything snap-related, as Wekan was one of the first snaps I’ve ever tried and is (or would be) the only one (besides core) currently installed on these systems.

All systems are running Ubuntu 16.04, with my (affected) desktop having both HWE and -proposed enabled, my (affected) server running a 4.4-series kernel (no HWE or -proposed) and the other (unaffected) desktop having HWE but no -proposed. The (unaffected) VM starts with kernel 4.4 and remains unaffected if I upgrade it with HWE.

I’m submitting this from the (HWE+proposed-enabled) desktop, so any logs attached here are from one of the two affected systems. I’ll of course provide other logs too if requested.

(This came up for me in Wekan issue #1389)

When I try to install the snap (in Ubuntu 16.04), it gets stuck in Run configure hook of "wekan" snap if present. At this time Wekan service is already up and running, but snapd gives up on the configuration after a (built-in) 5 minute timeout and undoes the installation. (I initially thought the Node process was misbehaving, but I no longer think that’s the case here.)

Wekan snap issue #10 seems like the same problem. I enabled snap debugging as mentioned there, and will attach the result of grep snapd from during the installation attempt here.

While the service is up during the configuration phase, it produces journal log entries as usual and I’m attaching the relevant lines here.

I’ve tried purging and reinstalling snapd, disabling IPv6, turning off Apache and any other services that might be in the way (though none of them have caused issues previously), rebuilding the snap with my previous settings built in but none of it has made any difference.

In addition to my main server, I’ve since reproduced this on my desktop machine, and failed to reproduce it on another desktop and a VM with a fairly clean Ubuntu 16.04 install. The only difference between the reproducing and non-reproducing systems I’ve so far found is an Apparmor denial in /var/log/kern.log:

apparmor="DENIED" operation="open" profile="snap.wekan.mongodb" name="/sys/block/" pid=9478 comm="mongod" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

The systems where Apparmor denies mongodb’s access to /sys/block get stuck at the configure hook, whereas systems that don’t report a denial finish the configuration (and installation) successfully.

I haven’t done any customization of Apparmor rules on any of these that I can remember; it’s pretty much dark arts to me which is why I’ve avoided touching it.

I noticed that the service is up locally during the (non-finishing) configuration phase, and produces journal log entries as usual, I’m attaching the relevant lines here. The gist of it appears to be an ”Error: no hostname or hostnames provided in connection string” from programs/server/node_modules/fibers/future.js:280

I’m unable to reproduce this snap issue in a VM, but so far I’ve failed to pinpoint the curcial difference between the VM and my physical server.

I’ve tried purging and reinstalling snapd, disabling IPv6, turning off Apache and any other services that might be in the way, rebuilding the snap with my previous settings built in but none of it has made any difference.

@xet7 Unfortunately the install now also fails with the same configure hook issue as refresh did:

root@battra:~# snap remove wekan
wekan removed
root@battra:~# snap install wekan
error: cannot perform the following tasks:
- Run configure hook of "wekan" snap if present (run hook "configure": )

(For mongodump, I had to replace/upgrade the Xenial package with mongodb-org-tools from the main MongoDB site, because Xenial’s mongodump 2.6 failed with assertion: 17369 Backing up users and roles is only supported for clusters with auth schema versions 1 or 3, found: 5. With mongodump 3.6.2 I was able to dump the db successfully.)

I came across this old Wekan snap report about the same issue. I enabled snap debugging as mentioned there, and will attach the result of grep snapd from during the installation attempt here.

Should I open a new issue about this, to keep this report on topic?

@xet7 When I try to refresh the snap, it gets stuck in Run configure hook of "wekan" snap if presentwith a node process eating up the CPU. It takes 5 minutes before snapd gives up. Now the service won’t come back up, and revert also fails:

root@battra:~# snap revert wekan
error: cannot perform the following tasks:
- Run configure hook of "wekan" snap if present (run hook "configure": )

For me the double slash regression occurred at 0.62-3-g74877fd (as it did for the reporter in #1405), whereas this edge-to-edge URL issue was already there in 0.60 (but the double slash issue wasn’t). It might not definitely make them completely unrelated, but would at least hint towards it.

Impacted version: 0.60

Server Setup Information:

• Operating System: Ubuntu 16.04
• Deployment Method: snap
• ROOT_URL environment variable (Is there a subfolder?): https://my-domain.com/kan (yes)

Problem description:
A description consisting entirely of a URL that happens to extend from the left edge to the right edge of the description field makes it impossible to edit the description, as clicking anywhere on the viewer lands the click on the URL, which triggers a new browser tab instead of the editor.

Here’s a screenshot of such a URL overlapping the editing area, as highlighted by the inspector in Firefox.

There’s actually a couple of pixels worth of unlinked, clickable editor area at the right edge here, but you need a really steady hand and mouse to hit those pixels.

A workaround seems to be to change the browser zoom level (either way), causing the URL to extend either over to the next line or properly short of the right edge of the first line (turning the rest of the line clickable).

With WP_DEBUG enabled, a non-existing page (404) logs the following PHP error:

Trying to get property of non-object in wp-content/themes/cover2/components/header/header-overlay.php on line 53

I believe this is caused by the $post reference on that line, as $post has not been populated on a 404 page.

After upgrading to Quantum, the right mouse button context menu for HTML links pops up in the wrong place when the Firefox window is pushed to either side of my screen (so that the window takes up half of the horizontal space). The issue appears similar to what has been reported in bug #1721614 (particularly as it appears in the video attached by the submitter), but for me the issue does not occur with the hamburger menu or other UI elements, only with links on webpages, and the menu highlighting behavior is different: in my issue the highlighting occurs normally only once I point the cursor at the menu.

== Steps to reproduce ==
1. Create a new profile and start Firefox using the profile.
2. Expand the window to fill the screen (if not already).
3. Enter search terms into the URL bar and hit enter to bring up a search results page.
4. Right-click a search result title to bring up the context menu. Left-click outside it to close it.
5. Grab the window title bar and push the window to the right edge of screen to resize the window to span half of screen horizontally. Release the title bar.
4. Right click the search result title again.

== What happens ==
The menu pops up on way off from where the mouse cursor is. See attached screenshot.

== What should happen ==
The context menu should pop up next to mouse cursor.

== Possible culprit ==
This seems to be somehow tied to localization: if I uninstall firefox-locale-*, then create a new Firefox profile, with this new profile the menu pops up where it should. I’m using Finnish locale, but this is reproducible with just firefox-local-en too, although the mispositioning differs between locales (Finnish pushes the menu off to the left, whereas English pushes it down and to the right).

== Workaround ==
Don’t right-click on the page before resizing the window (that is, skip step #4 above). This seems to be the trigger.

== Other info ==
I’m able reproduce this in a (16.04) VM just as well as on the host desktop.
