Question

chromium browser timeout when trying to download PDF/PNGs


We are trying to use some Looker features that utilize the chromium-browser, like downloading a PDF or PNG. However, when we choose to download something, a chromium-browser process starts to render the PDF, and the process never finishes.

When we show the process-list, with hierarchy, we can see the processes running (they have --type=renderer) but it always times out. See below:

The one kernel of relevant information we were able to find was in dpkg.log from last week where it looks like Looker automatically tried to update chromium. We are unsure if these logs resemble a successful load, but we are pretty sure this is when the problems started happening.
