FEX unable to work - can't set rootFS, trying to rerun the script gives PPA failed to install

I'm trying to get steamCMD running so I can easily manage a server software that's only x86 compatible. After setting up FEX, I am certainly sure that I configured rootFS from the installer. yet I can't run SteamCMD, as it reports
Invalid or Unsupported elf file. This is likely due to a misconfigured x86-64 RootFS Current RootFS path set to '' RootFS path doesn't exist. This is required on AArch64 hosts Use FEXRootFSFetcher to download a RootFS
Rerunning the installer gives
PPA failed to install apt sources failed to update. Not continuing
PPA Status reports as installed in the download log btw. I'm unsure what to do

This is an OCI Ampere instance with ubuntu 22.04.5

Sounds like you might have changed user accounts for that error message to come up.
Would need to rerun FEXRootFSFetcher on that user account to get the rootfs setup, which is a per-user install.

Oh it's probably that. Ty will try later

Do you know how can I just clean reinstall all of FEX and reconfigure it properly?

sudo apt-get remove fex-emu* and rm -Rf $HOME/.fex-emu/ for removing everything the install script does.

Default script configuration just installs a couple of packages and runs FEXRootFSFetcher
