TW - Cant remove own files

H, dunno if this is a quirky on TW 20221004, or a more general issue, but I cant remove files which I own: docb@X1E:~/Downloads> whoami docb docb@X1E:~/Downloads> dir openSUSE-MicroOS-DVD-x86_64-Snapshot20220719- Media.iso -rw-r--r-- 1 docb users 4018143232 23. Jul 20:12 openSUSE-MicroOS-DVD-x86_64- Snapshot20220719-Media.iso docb@X1E:~/Downloads> rm openSUSE-MicroOS-DVD-x86_64-Snapshot20220719- Media.iso rm: cannot remove 'openSUSE-MicroOS-DVD-x86_64-Snapshot20220719-Media.iso': Permission denied Deletion works only as root. Anyone seen his before? Cheers Axel
