Moving, the entire directory ~/tmp (on tmpfs), makes it not fail and successfully build the AppImage

[baryluk]

It is sshfs bug. https://github.com/libfuse/sshfs/issues/250

Sorry for the noise here. I just never experienced this issue despite me using sshfs daily for last few years, until I tried appimage-builder.

[baryluk]

It looks like the bug is actually in the tar. tar -x -p -f data.tar.xz (after extracting manually data.tar.xz using ar x libc6*.deb), shows same issue.

tar correctly passes AT_SYMLINK_NOFOLLOW. And the file it is trying to update utime exists:

lrwxrwxrwx 1 user user 32 May  7 17:00 ./lib64/ld-linux-x86-64.so.2 -> /lib/x86_64-linux-gnu/ld-2.31.so

Maybe it is a bug in the FUSE. Anyway, closing, as this is not appimage-builder issue.
