Please describe your issue:

I cannot open my chroot (Debian Buster LXDE) using startlxde, I installed it onto a USB Drive, and the startlxde file is in a folder called "bin" on the USB Drive, and there is also a "chroots" folder. How do I execute startlxde, and how do I make sure it executes buster from my USB Drive?

If known, describe the steps to reproduce the issue:

No bugs, just inability to do what I intended.

You can first cd into your external media device to the root directory in which you installed the bin and chroot subdirectories and data. Then launch your lxde desktop with: sudo sh ./bin/startlxde

Hope this helps,

It returned with sh: 0: Refusing to exec ./startlxde from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md, does this mean it is non-executable?

Check where and how it's mounted with:

• mount | grep /media/removable

Take note of the name of the mount point.
Then if you see a 'noexec' in the mount options remount it with:

• sudo mount -o remount,exec /media/removable/USB \Drive

If the mount point is named something other than 'USB Drive' then use that name.

It didn't say anything about noexec, but your solution did just the trick! Now I just need to export the chroot to a tarball and I'll be set with a Debian VM. Thanks a lot.
