@rolandog Is the behaviour same on earlier ubuntu versions. Also can you try building from sources?

[rolandog]

Hey @kanurag94 , thanks for your response.

I would've sworn I ran into the same issue when running on 20.10 at the beginning of this year. But I only tried XaoS for a short while and I didn't have the time to submit a bug back then. Since then, I have upgraded Ubuntu to 21.04 and then to 21.10, and had a bit more time to play with XaoS.

Here's the output of `zgrep` on `dpkg` logs:

As for building, do you want me to try to build on a particular tagged branch?

[kovzol]

Same on Ubuntu 22.04 (daily build), I think it is worth reporting to Ubuntu (or Debian) maintainers directly, because this should have been fixed in the sources (on the main branch).

[leahneukirchen]

I don't get this fix at all, and also release 4.3 hangs here.

tabhishek432@67a9c26#diff-7c8e040d1982db3517521e9ab5d9769e8872ea89aa5028946395215d51c1c21bR174 tries to read ../examples (from current pwd) and the whole thing just hangs if that directory doesn't exist.

[kovzol]

You seem to be right, I'll try to fix this asap.

[kovzol]

I guess I fixed this.

[leahneukirchen]

Works, thanks!
