I know unplugging a raspberry without shutting down property is a sin, so what do I do if it's frozen and nothing is responding?

I waited about 10 minutes and it's still stuck.

Edit: I'm running Ubuntu 20.10 on a Raspberry Pi 4 I was transferring some files to an external hard drive when it froze. The Mouse and keyboard wasn't responding.

  • Welcome to Ask Ubuntu. The answer depends on whether you are using the Raspberry Pi OS or Ubuntu, and which version. Please update your question with the new information. If you are using Raspberry Pi OS, then see this discussion – user68186 Mar 18 '21 at 19:27

    Well, it's a forgivable sin. There is pennance you must do afterward (a filesystem check - fsck). It risks data loss. But if your system is frozen, then we have all needed to unplug at some time. – user535733 Mar 18 '21 at 19:41
  • 10 minutes may not be long, depending on what it was doing... SysRq commands go direct to the kernel bypassing and user-space programs (including the GUI) that may have frozen allowing a safe shutdown; you can also sometimes ssh in from remote to explore & shutdown the box gracefully... but I'd opt for using SysRq and commands on the device direct to the kernel. You provided no detail on what is doing; for some tasks 10 minutes is not long at all (I often leave machines overnight or 36 hours before I sysrq) - but I don't know what you were doing. – guiverc Mar 19 '21 at 02:06
