The root of you issue is the libc6 update causing snapcraft to segfault when running ldd, we are working on a work around in snapcraft for this which will come out as 4.6.3.

I have spoken to foundations to see how soon we can get a spin of core20 as well.

Is there a workaround to this issue? Otherwise, how long might we expect it to take to have a fix released for core20?

Thank you.

If you are affected by the “Unable to determine libraries …” issue with classic confinement, there is a PR in progress which you can test by using snapcraft from the edge/pr-3514 channel. This will be out today.

core20 will be updated sometime tomorrow or the day after depending on testing results.

egmde is fixed when using Snapcraft from edge/pr-3514

edge/pr-3514 fixes the dependency problems for me too, thanks for all the help

I created a patchset for the gnome-3-38-2004-sdk snap which hopefully would get reviewed tomorrow.

I made a call for testing for Snapcraft to solve one of the common issues mentioned here Call for testing: Snapcraft 4.6.3
