Downgrading to signal-desktop.x86_64 0:1.33.4-1.el7 works as expected.

[luminoso]

Thank you for testing. I'm going to try to reproduce the issue.

I anticipate that this may be a upstream problem, since there's close to no difference between 1.33.4 and 1.34.2 spec file :thinking:

[luminoso]

Oh boy.. Signal included yet another binary in their release and it looks like it is the source of the problem.

The library is built against GLIBC_2.18 while el7 has GLIBC_2.17

To solve it looks like that libzkgroup.so from signal-zkgroup-node must be rebuilt. hum.

Thankfully, other people are facing the same issue so that I can take some ideas from :-)

I'll try to do this. If you have any other idea let me know

[luminoso]

Ok just made a new build. c6a1530 should fix the issue.

Can you please update your system to see if the fix also works for you?

[dtrash1]

The latest build completely solves the issue on my configuration. Thanks!
