Insync not able to resolve apt.insync.io Debian Bullseye [FIXED]

Bugs and issues Linux
1

I tried to install insync on opensuse-tumbleweed and then on Linux Mint Debian (LMDE5). Both times the client was not able to contact or resolve apt.insync.io or yum.insync.io (I think).

This is a copy of what I see when I try to update:
“sam@sam-nuc10i7fnh:~$ sudo apt update

Any ideas?

Exactly the same for Ubuntu 20.04, neither insync.io, nor apt.insync.io can’t be resolved (no A records whatsoever).

Thank you for reporting the issue. I’ve alerted our Linux team regarding this and will be updating you!

Hello! This has been fixed. Please try again!

Thanks Mia,

It seems to be working again. Did a server get unplugged? Lol.

No, it expired but seems like we didn’t get alerted prior😅 We’ll be more proactive with this to prevent any trouble on your end!

I’m still seeing this but for Ubuntu:

➜ sudo apt update; apt list --upgradable
...
Err:10 http://apt.insync.io/ubuntu jammy Release
404  Not Found [IP: 0.0.0.0 80]

E: The repository 'http://apt.insync.io/ubuntu jammy Release' no longer has a Release file.

Notice the 0.0.0.0. I’ve never blocked that host, but when I explicitly added insync-apt.b-cdn.net to my allow list in Pi-hole:

Did insync-apt.b-cdn.net get added to a deny list?

Hmm, OK, so at some point, not sure when, I must have blocked b-cdn.net because I see it in my block list. I’m not sure when that happened because I’ve been out of town for the last few days, so… :confused:

False alarm!

@jc00ke Thanks for updating us that it’s been sorted out. I appreciate it!
