[Solved] apt problem with dns

[fabien]

Hello Probzx, thank you for the strace file.

What are you looking for in the strace report?

I'm looking for things like just above, or things like below that I missed:

Code: Select all

openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
newfstatat(3, "", {st_mode=S_IFREG|0770, st_size=24466, ...}, AT_EMPTY_PATH) = 0
[...]
openat(AT_FDCWD, "/usr/share/locale/locale.alias", O_RDONLY|O_CLOEXEC) = 4
newfstatat(4, "", {st_mode=S_IFREG|0770, st_size=2996, ...}, AT_EMPTY_PATH) = 0
[...]
newfstatat(AT_FDCWD, "/etc/debian_version", {st_mode=S_IFREG|0770, st_size=5, ...}, 0) = 0

The standard permissions are as follows:

Code: Select all

stat -c '%A %a %U %G %n' /etc/ld.so.cache /etc/locale.alias /etc/debian_version
-rw-r--r-- 644 root root /etc/ld.so.cache
-rw-r--r-- 644 root root /etc/locale.alias
-rw-r--r-- 644 root root /etc/debian_version

Please fix the permissions and test again.

It looks to me like you changed the permissions in /etc/ a lot. You are in a better position than I am to examine and correct them.

At some point, if it still doesn't work, you could do the previous procedure again, although I still don't know why it worked.

Thanks, have a nice weekend!

Hello Fabien,

Thanks a lot for your answer !
I started to correct all the files on the /etc/ folder, then remove the trusted.gpd link in order to keep only the .asc files on /etc/trusted.gpg.d.
I retrieved apt update and it works without any error or warning.
All my files in /etc have wrong permissions settings compare to a fresh server.
It's pretty long but I change half on the permissions files for now.

Hello Probzx,

apt update [...] works without any error or warning.

This is great news!

Do you think it's possible to "repair" my apt ?

Yes it is!

I think it's time to mark your topic as resolved. You can do it by editing your first post and adding [Solved] to the title, e.g.
[Solved] apt problem with dns
but please keep letting us know how you get on with your server.
Have a nice day!

Hello @Probzx,

As @fabien suggested in his previous post, please, mark the discussion as "solved" manually adding the text tag "[Solved]" at the beginning of the subject of the first message (after other tags, if any). It is also an opportunity to the make the subject more understandable to other forum users and readers, if necessary; i.e. :

[Solved] apt problem with dns due to misconfiguration/etc directory

Thanks !
