Hi there, I upgraded my Linksys E8450 to 24.10.1, and since then the backups generated with both LuCI and cli are unreadable...
I upgraded a Xiaomi AX3200 as well (upgraded without keeping the config, set up everything from zero), and the result there is the same as well. The tar file in the gzip archive is unreadable in both Linux and Windows. What can I do to drill down into what's causing this? I've even tried installing tar with opkg so as not to rely on the busybox version, but no dice.
Edit: if I tar up all the files that are shown in the Backup/Flash / Configuration by clicking on "Open list", with "tar -czvf /tmp/trial.tar.gz -T /root/filelist", the resulting tar.gz file is perfectly readable.
I used the above command as per the netbird manual, as the owrt repo is behind the official one with several versions. I'm don't know what the install script could contain that messes up the backup creation...
As I said, if I take the list of files that come up by pressing "Open list" and put them in a text file, and use that to tar everything up, the resulting file works. So somehow the sysupgrade routine fails after installing netbird with the above command line...
Edit: I bit the bullet and uninstalled the netbird client that got installed from the script above (service and binary), and installed the unfortunately outdated version from the owrt repo. Config backup works now. Seems that how the service gets installed with the script messes up sysupgrade.
