I'm trying to install PySide6, which requires qt6-main, using Conda. During the install using the command

conda install qt6-main -c conda-forge

I get the error:

InvalidArchiveError('Error with archive C:\\Users\\Username\\Anaconda3\\pkgs\\qt6-main-6.4.2-hc84ccb7_3.conda.  You probably need to delete and re-download or re-create this file.  Message was:\n\nfailed with error: seeking backwards is not allowed')

I have tried and this happens for versions 6.4.2 to 6.4.0. Is this a problem with Conda, with the archive or with something else?

  • What version of Conda? Did you try deleting the file from the package cache and reinstalling? Since this has to do with the `.conda` format, you may want to update `conda-package-handling`, e.g., `conda update -n base conda conda-package-handling`. – merv Feb 06 '23 at 22:57
  • Try cleaning your conda package cache with `conda clean -a` – Saaru Lindestøkke Feb 06 '23 at 23:36
  • Yes, I tried deleting the downloaded file. `conda` and `conda-package-handling` are both up to date (version 23.1.0 and 2.0.2 build py39haa95532_0 resp.) – LimaKilo Feb 07 '23 at 08:57
  • I can't replicate any decompression issue: `wget https://anaconda.org/conda-forge/qt6-main/6.4.2/download/win-64/qt6-main-6.4.2-hc84ccb7_3.conda` and then `cph x qt6-main-6.4.2-hc84ccb7_3.conda` work fine. Using `conda-package-handling=2.0.2` on **osx-64**. – merv Feb 07 '23 at 15:51
  • For me, your `cph` command gave more insight: It threw the error `File "C:\Users\username\Anaconda3\lib\tarfile.py", line 2252, in makelink os.symlink(tarinfo.linkname, targetpath) OSError: [WinError 1314] Dem Client fehlt ein erforderliches Recht: '..\\lib\\qt6\\bin\\qmake.exe' -> 'D:\\username\\temp\\qt6-main-6.4.2-hc84ccb7_3\\Library\\bin\\qmake6.exe'` this exception is handled in the tarfile script, but during the handling, the exception from the title comes: ` File "C:\Users\username\Anaconda3\lib\tarfile.py", line 515, in seek raise StreamError("seeking backwards is not allowed")` – LimaKilo Feb 09 '23 at 17:15
  • So the script can't generate the symlinks it wants to, and during the exception something else happens. I was able to extract the package without the error as admin, but that workaround shouldn't be needed - all the rest of Anaconda works fine as a normal user – LimaKilo Feb 09 '23 at 17:18

I was getting the same error, before uninstalling/reinstalling(and updating) Anaconda3. Now, I'm getting something different, but still with the same "smell":

I can't get Anaconda Prompt to launch, either as Admin. or regular user. So, I can't try that experiment. And sudo doesn't work in MINGW on Windows. So, I can't tell if it's a permissions thing. :(

I faced the same issue on Windows with up-to-date conda and conda-package-handling. Works fine on Linux.

I filled a bug at https://github.com/conda/conda/issues/12369

While waiting the feedback of issue filed by Nicolas , I tried conda install pip first and then pip install pyside6. It shows in conda list and the packages are also under venv's site-packages. I am using that as work around for the time being..FYI.
