When I try to pull and extract code for a docker container, I get: root@nextcloud:~# sudo docker pull collabora/code Using default tag: latest latest: Pulling from collabora/code bd97b43c27e3: Pull complete 6960dc1aba18: Pull complete 2b61829b0db5: Pull complete 1f88dc826b14: Pull complete 73b3859b1e43: Pull complete 0f0e2d01915e: Pull complete 2458b914d686: Pull complete a3e2abb56fa4: Extracting [==================================================>] 972.1 MB/972.1 MB failed to register layer: ApplyLayer exit status 1 stdout: stderr: operation not permitted Additionally, when I went to delete the btrfs subvolumes created by docker (maybe related to [ https://lists.linuxcontainers.org/pipermail/lxc-users/2015-February/008494.html | this issue ] ?): root@nextcloud:/var/lib/docker/btrfs/subvolumes# rm -rf * rm: cannot remove '3398c42dda6ee295d52d593a0e5334dd51a172826e5881ec9dff84bc37315c8d': Operation not permitted rm: cannot remove '37b4ed38bb85b4140ab416ff74317968e4e18fd2ffadb74236cfb4b4254f785b': Operation not permitted rm: cannot remove '44474f3511f76cda0cb0f4227c59981e8a830fc90f17a2e9376e0f6b35842590': Operation not permitted rm: cannot remove '5a7b74cc5a0e14d161d5ea942001b83812021260722e64da27cb315a52d6fa70': Operation not permitted rm: cannot remove '6b359e6c6a5714c0e227a444601c7d4c4ab281079ebecf712b772c553e52f65f': Operation not permitted rm: cannot remove '76ecc26b9fd080267c4e937f80b0993ce0e637847240f36dd3c434eae01fbb37': Operation not permitted rm: cannot remove '77e3c37a5af37ff8e66fe58349afac618882ac684de3231ffe12a163e9c7211f': Operation not permitted rm: cannot remove 'b62a1c869c9e9b7dbc8693b7b97c14cb7ccf09b3bf52e0d6a7656cc3bb50c312': Operation not permitted rm: cannot remove 'b9677d2c91cd0ccc00f8b557b56c103390c777b3e2574aee3a35595224665d75': Operation not permitted rm: cannot remove 'e3db5dcb5a3e25caae66eed98976d46ec46f17a0a3e3e94e0985635fc614ec54': Operation not permitted Which I'm assuming is the same issue causing: r oot@nextcloud:/var/lib/docker/btrfs/subvolumes# sudo apt remove --purge docker.io Reading package lists...

Question 2: Does the btrfs subvolume issue mean that any subvolume in a container can't be removed? If it can, what's the proper way to remove them? Best Regards, Lai Wei-Hwa IT Administrator T.
