问题
There was an error when I tried to remove a package, so it was left in a broken state. I tried the following:
sudo dpkg --remove --force-remove-reinstreq rvm
Output:
(Reading database ... 41743 files and directories currently installed.)
Removing rvm (1.29.3-1) ...
bash: rvm: command not found
dpkg: error processing package rvm (--purge):
subprocess installed pre-removal script returned error exit status 127
Errors were encountered while processing:
rvm
.
sudo dpkg --purge rvm
Output: same as above
sudo dpkg -i --force-overwrite package
Output:
dpkg: error processing archive rvm (--install):
cannot access archive: No such file or directory
Errors were encountered while processing:
rvm
Is there a way to force remove it, ignoring all errors? I'm using Ubuntu 16.04 on WSL.
回答1:
I faced this problem with a broken package, rvm. I tried many things like sudo apt install -f and sudo dpkg --purge --force-all rvm but nothing worked. Finally I managed to find this blog post that explains how to remove broken packages on Debian/Ubuntu.
Here are the steps.
- Find your package in
/var/lib/dpkg/info, for example using:ls -l /var/lib/dpkg/info | grep <package> Move the package folder to another location, like suggested in the blog post I mentioned before.
sudo mv /var/lib/dpkg/info/<package>.* /tmp/Run the following command:
sudo dpkg --remove --force-remove-reinstreq <package>
So as an example I solved my problem by executing the following commands in a terminal:
sudo mv /var/lib/dpkg/info/rvm.* /tmp/
sudo dpkg --remove --force-remove-reinstreq rvm
回答2:
Execute the command as a root
sudo apt-get install -f
You need elevated privileges for the package manager.
