Once you have enough packages restored, try to run yum again, it might end up upgrading packages again. The attribute listed as 5 is the MD5 checksum of the file, that means the contents of that file have been altered. This will list files in the package which have had at least one attribute modified. You can also verify whether files from a specific package have been overwritten with: $ rpm -V python-libs To list all packages matching python-*, you can use: $ rpm -qa 'python-*' You might need additional options such as -force and -nodeps, but the idea is that you manage to reinstall the package and overwrite the Python package back to the 2.7 (even if a slightly older versions, with not all the updates) from CetnOS. You can download them from the same location (Warning: long directory listing here, it might take a while to take the whole list.) It is possible that this is not the only package you'll need, I suggest you look at all the packages starting with python-*, since many subpackages ( python-libs is one obvious case, but there might be others) might have been overwritten as well. Using -oldpackage will allow you to reinstall the same version, or even install an older version, which is possible since you might have gotten package updates that are more recent than version you downloaded.)
(The rpm -F command, -F for "freshen", will update packages that were already installed. Then, change directory to the one where you downloaded the package to, and install it using: $ sudo rpm -Fvh -oldpackage python-*.rpm Since yum is not working, you'll have to do most of it manually, by downloading the packages and reinstalling them using rpm directly.įor example, you can find a Python 2.7 RPM here (for CentOS 7 on x86_64): (See below as for why you should reinstall, and how you should manage newer versions of software in a distro such as CentOS.) Reinstalling older Python from RPM To fix this problem, you should reinstall Python 2.7 shipped with CentOS 7. Copied, almost to the word, from Solution #!/usr/bin/python >-Replace with ->#!/usr/bin/python2 Solution 1, enter the edit urlgrabber-ext-down Loading mirror speeds from cached hostfileįile "/usr/libexec/urlgrabber-ext-down", line 28
The error leading to this problem was:įound that yum no matter what software is installed, is an error, the type is as follows: base) ~]# yum install yum-fastestmirror There was a problem importing one of the Python modules Then you can modify the yum code python to python to implement.Ĭhange #!/usr/bin/python on the first line to #!/usr/bin/python2. Type "help", "copyright", "credits" or "license" for more information. If you can enter python2 by building python2 (base) rstudio]# python2 If this is what you see on yum install (base) rstudio]# yum install shiny-server-1.5.9.923-x86_64.rpmīecause yum supports python2 by default, when you upgrade to python3, you get an error.
