How can i access the link? It says Authentication Error. You do not have access to this workspace

From my research this issue is with Ubuntu 24.04.2 LTS x86_64 because it comes with ffmpeg 6 and the required library is in the apt store, but only for Ubuntu 25.04 (latest non LTS)

Package libavcodec61
plucky (25.04) (libs): FFmpeg library with de/encoders for audio/video codecs - runtime files [universe]
7:7.1.1-1ubuntu1: amd64 arm64 armhf i386 ppc64el riscv64 s390x

So is it safe to say that SpaceDrive will not work on Ubuntu24.04? What is the workaround here?

I am wondering the same thing.

[tsmcmurphy]

Did some investigating and found a workaround.

Context:

My OS is Linux Mint 21.3, but this process should work for any Ubuntu based OS.

The library is in the deb package

$ dpkg-deb -c Downloads/Spacedrive-linux-x86_64.deb | grep 'libavcodec.so.61'
lrwxrwxrwx root/root         0 2025-03-02 18:47 ./usr/lib/Spacedrive/libavcodec.so.61 -> libavcodec.so.61.19.100
-rw-r--r-- root/root  43887432 2025-03-02 18:47 ./usr/lib/Spacedrive/libavcodec.so.61.19.100
lrwxrwxrwx root/root         0 2025-03-02 18:47 ./usr/lib/Spacedrive/libavcodec.so -> libavcodec.so.61.19.100

The library is installed by the deb package into the filesystem

$ dpkg -S libavcodec.so.61
spacedrive: /usr/lib/Spacedrive/libavcodec.so.61.19.100
spacedrive: /usr/lib/Spacedrive/libavcodec.so.61

But the OS doesn't know they are there.

$ ldconfig -p | grep libavcodec.so.61
# no output...

$ grep '/usr/lib/Spacedrive' /etc/ld.so.conf /etc/ld.so.conf.d/*.conf
# no output...

Workaround

Manually add the path to /usr/lib/Spacedrive to the OS's library path

$ echo "/usr/lib/Spacedrive" | sudo tee /etc/ld.so.conf.d/Spacedrive.conf
$ sudo ldconfig

[DarthMatter17]

The RUNPATH tag in the binary doesn't match the directory where the library is installed.

$ readelf -d /usr/bin/spacedrive

Dynamic section at offset 0x48c8bf0 contains 47 entries:
  Tag        Type                         Name/Value
...
 0x000000000000001d (RUNPATH)            Library runpath: [${ORIGIN}/../lib/spacedrive]

So the linker searches for the library in ${ORIGIN}/../lib/spacedrive while it's actual location is ${ORIGIN}/../lib/Spacedrive

Workaround

Add a symbolic link
$ sudo ln -s /usr/lib/Spacedrive /usr/lib/spacedrive
