I think something's wrong with the container's DNS resolver can you curl 1.1.1.1

Mrugendra KulkarniOP•3y ago

The same issue is happening for new container (ubuntu).Output for

ping google.com

ping google.com

ping: google.com: Name or service not known

@Mrugendra Kulkarni, you've gained the level 1

Asterisk•3y ago

yup it's a DNS issue

Zephyr•3y ago

Someone else had a similar issue recently, do you remember if/how they solved it?

Asterisk•3y ago

can you show the container's /etc/resolv.conf?

Mrugendra KulkarniOP•3y ago

cat /etc/resolv.conf
# Generated by NetworkManager

cat /etc/resolv.conf
# Generated by NetworkManager

This is third time now third container

Asterisk•3y ago

can you run nmtui in the container?

Mrugendra KulkarniOP•3y ago

Nope not found

Asterisk•3y ago

and run resolvectl status

Mrugendra KulkarniOP•3y ago

sd_bus_open_system: No such file or directory

sd_bus_open_system: No such file or directory

Asterisk•3y ago

Mrugendra KulkarniOP•3y ago

Asterisk•3y ago

so stuff on your main container works *your host

Mrugendra KulkarniOP•3y ago

Yes

Asterisk•3y ago

yeah @Zephyr I can't find what they did

Zephyr•3y ago

Did you try with a non-Ubuntu container? If not, can you?

Mrugendra KulkarniOP•3y ago

Sure Done ping is workin in arch container But now the problem is this

$ sudo pacman -Syy
bash: sudo: command not found
$ su
Password: 
su: Authentication failure
[mrugendra@arch ~]$

$ sudo pacman -Syy
bash: sudo: command not found
$ su
Password: 
su: Authentication failure
[mrugendra@arch ~]$

So now I have to install packages from terminal (host)? Output on host

$ sudo pacman.arch -Syy
:: Synchronizing package databases...
error: failed to synchronize all databases (unable to lock database)

$ sudo pacman.arch -Syy
:: Synchronizing package databases...
error: failed to synchronize all databases (unable to lock database)

Zephyr•3y ago

Sudo not found on your arch container is..weird? You can use podman in host to check the logs of your Ubuntu and arch container to see if there are any issue maybe?

Mrugendra KulkarniOP•3y ago

How to do that? Please help me, I had created new debian container and at first it had internet access, but after restarting it was unable to connect.

Gris•3y ago

I have the same problem here, did you find a solution?

Mrugendra KulkarniOP•3y ago

No bro not yet The internet is working fine in container but after a restart it just stop working

Zephyr•3y ago

I haven't been able to recreate this issue, so all I can say is try to provide as many details as possible (especially podman logs for the container) Does it only happen to containers created prior to the current boot, or all containers? (if you create a new instance of the same distro that you can't get internet on, does it work in the new one?) Does it only work before the first time you restart blendOS, and then never again after that, or did it work for some restarts and then stop working?

Mrugendra KulkarniOP•3y ago

At the beginning, it works flawlessly, but after reboot it stops working, after creating new container, it also get same issue, can you send e docs for podman to get logs . Creating new container of same distro get internet at beginning but then same issue occurs ( sorry for my bad English)

Mrugendra KulkarniOP•3y ago

This is the output I am getting

Mrugendra KulkarniOP•3y ago

Internet started working after kill and start of the container but why it is occurring at first ? UPDATE: Internet on the container is still not working, but after restarting them with podman, it works fine Why this is occurring ?

Zephyr•3y ago

Interesting, good to know that restarting them with podman is a temporary fix, though 🤷‍♂️

Mrugendra KulkarniOP•3y ago

Yes but what should be permanent fix?

Zephyr•3y ago

I don't know. I'll create an issue on the github for this if one doesn't exist, so we can track it, and figure out where the problem comes from. It could be a misconfiguration by blendOS, or simply a bug in podman container autostart behavior.

Mrugendra KulkarniOP•3y ago

Ok thanks

Zephyr•3y ago

https://github.com/containers/podman/issues/8047 I'll check if the podman version running in blend has this issue fixed or not
