No internet connection on newly installed Linux Mint

[quacksilver]

I'm a linux beginner and installed my Linux Mint, Cinnamon 20 distribution a few days ago.
To use Notepad++, I installed wine-9.0 (Ubuntu 9.0~repack-4build3) following the instructions of https://gitlab.winehq.org/wine/wine/-/w ... ian-Ubuntu (installing "wine-stable", since "winehq-stable" doesn't exist)
Now I wanted to install a program which needs an internet connection, but it only gave me an error.
Via cmd.exe's ping, I found out that wine-translated executables don't have an internet connection (PING: transmit failed. General failure.).
DNS Resolution works fine though (ping translates host names into ip adresses), so it seems to be a http/https issue.
After running cmd.exe with sudo (I know you shouldn't do that) the ping command worked perfectly fine, meaning an internet connection could be established. I'm already sitting here since two hours, having no idea what to do.

I already tried:
DLL Overrides via winecfg GUI (native/builtin)
Googling (all first page search results).
Deactivating linux firewall.
Reinstalling "wine" package.
Reinstalling "winbind" package.
chmod -R +rwx ./.wine
.wine/log.txt outputs nothing when trying to connect to internet
cmd.exe's ipconfig /all's output seems to be fine (which should be, since DNS resolving works).
Debugging wine via WINEDEBUG environment variable (if that nonsense cryptographic text can help you I will post it)

Maybe this is realted:
When starting wine as super user, the following message pops up (which doesn't when not as super user): 0060:err:ole:start_rpcss Failed to start RpcSs service
I changed the registry key HKEY_CURRENT_CONFIG\Software\Fonts\LogPixels
I deactivated desktop integration (winecfg GUI)
I removed every drive letter association except C (winecfg GUI)
The command "wine iexplore" show a blank website and outputs: 017c:err:mshtml:create_document_object Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE
https://gitlab.winehq.org/wine/wine/-/w ... ermissions
https://forum.winehq.org/viewtopic.php?t=37381 seems to have the same issue.

If, for some reason, my installed packages are important, here is the output of 'apt list | grep "wine"':

FYI, you installed the Ubuntu distro wine package, not ours. There is no winehq-stable package yet for noble because noble was not yet released when 9.0 came out. We will have stable packages for noble when 10.0 is released in January. In the mean time, you can either stick with the distro stable package or install our winehq-devel or winehq-staging packages.

You also messed up the permissions in your wineprefix by running as sudo. Follow the instructions in the FAQ to fix it. https://gitlab.winehq.org/wine/wine/-/w ... ne-as-root

Thank you very much for your help!

I'm wondering why this isn't pointed out clearly, it would be a huge help for beginners like myself.
There is this notice on the installation guide "Although Debian and Ubuntu offer their own Wine packages",
but I just thought that some people from these distributions ported WineHQ to make it (everything, including internet) work on Ubuntu/Debian. Also, in the installation list, there is an entry for Linux Mint 22, so I concluded there would be support, which doesn't seem to be the case (?). Additionally, on askubuntu it says that the package is named wrongly in the installation guide and should be "wine". But whatever.

Again, thanks for your help.

PS:

You also messed up the permissions in your wineprefix by running as sudo

It apparently didn't. I don't have any issues and the .wine folder and cmd.exe is still owned by me.
