Hi,
I tried to download Inkscape through Ubuntu Software, Ubuntu 21.04, but before it could finish it returned this error: unable to install inkscape cannot perform following tasks:
As can everyone see, there aren’t any visible tasks… It’s blank and wasted my data plan trying to download that… (I don’t have unlimited internet…)
snapd shows the tasks it performed in snap changes, you should be able to get a list of tasks with that command, each with a change ID in front.
To get details of a specific change you can also do:
snap change <change ID>$ snap changes

Do the files exist, and have similar checksums?

That’s really a bad joke, my data plan isn’t unlimited…
this honestly looks like some kind of network cut to me …
I’m facing constant USB Dongle alternation from 4G to 3G. Reported that on launchpad, but even if it’s network cut, shouldn’t daemon reestablish the download when network is available once again?
one would expect so, but i guess that’s rather a question to the snapd team in https://forum.snapcraft.io … i know that snapd already throttles the download speed if network-manager reports a connection as “metered” (i.e. 3G/4G) perhaps it cant cope as well as it should with the additional switching between 3/4G in that mode …
