@ufna: thanks for the report, this should be fixed in the latest version 4.1.0-3 I just pushed.

Currently proxmox-backup-client 4.1.0 does not build from AUR. Cargo fails because it requires proxmox-fuse ^1, but crates.io only provides proxmox-fuse 2.0.0.

error: failed to select a version for the requirement `proxmox-fuse = "^1"`
candidate versions found which didn't match: 2.0.0
location searched: crates.io index
required by package `pbs-fuse-loop v0.1.0 (...)`

@Vallic_Magnus Thank you for the clarification. In the end it was an indentation error that crept in during copying. >.<' But thanks for your patch anyway!

@dosenpils The "Hunk #1 FAILED" error usually indicates a context or whitespace mismatch between the patch and the clean source tree. I have updated the patch to use the exact context required for v4.1.x.

Please ensure you are applying this using the _apply helper in your PKGBUILD, which handles the -p1 strip level automatically.

@Vallic_Magnus I'm having troubles applying your patch manually. I cannot find this 'extract.rs' anywhere, that's why 'makepkg' is complaining about not being able to apply this patch:

patching file pbs-client/src/pxar/extract.rs
Hunk #1 FAILED at 1337.
1 out of 1 hunk FAILED -- saving rejects to file pbs-client/src/pxar/extract.rs.rej

The package currently fails to build with Rust 1.88.0+ due to a borrow-checker error (E0716) in the pbs-client crate (pbs-client/src/pxar/extract.rs). This occurs because a reference is taken to a temporary String created by .to_string().

To fix this, ensure both match arms in the logging block return an owned String. I have verified this fix locally on Arch with rustc 1.88.0.

Latest Rust stable

x-mas today! PBS 4.1 released and a fresh, suitable and up2date client for Arch!
As always: Many thanks!

Thanks, mate! Meanwhile I'm doing the restore by "mount". Slow but working.

@OJaksch I'll look into doing a bump soon, hopefully later today but in any case still this week.
