~ $ gdalinfo --version gdalinfo：符号查找错误：/lib/libgdal.so.28：未定义符号：proj_crs_get_datum_ensemble

最近升级到 Ubuntu 21.04 并且事情停止工作，尝试删除所有 gdal、qgis 安装并再次重新安装，这是最新的。以前的错误是https://gist.github.com/adoug/f551c96ae49bcf0dd4905cfb3ed1c910。从 gui 安装 qgis 也会出现错误Unable to install QGIS Desktop: Error while installing package: installed qgis-providers package post-installation script subprocess returned error exit status 127

~ $ pip3 install gdal
Requirement already satisfied: gdal in /usr/lib/python3/dist-packages (3.2.2)
~ $ pip3 uninstall gdal
Found existing installation: GDAL 3.2.2
Not uninstalling gdal at /usr/lib/python3/dist-packages, outside environment /usr
Can't uninstall 'GDAL'. No files were found to uninstall.

整个安装似乎被破坏了，有没有办法清理所有并重新安装或以某种方式从中恢复？

不是为了修复当前问题，而是使用全新的 anaconda 安装作为解决方法，让 gdal 再次工作

conda update --all
conda install -c conda-forge gdal
