Solution to garbled PDF files in ubuntu8.04

I copied a PDF file from the USB flash drive, but when I open it, all Chinese characters are garbled. You can't bear to delete it, so you can search for the treatment method on the Internet.

1. Under the root permission, type: APT-Get install poppler-Data

2. Wait until the download is complete.

3. I did not know before. After the download, it was automatically decompressed and configured. I also typed the following:

# Dpkg-I poppler-data_0.2.0-0ubuntu1_all.deb
(Reading the database... the system currently has a total of 116317 files and directories installed .)
Preparing to replace poppler-data 0.2.0-0ubuntu1 (using poppler-data_0.2.0-0ubuntu1_all.deb )...
Extracting and replacing the package file poppler-data...
Setting poppler-data (0.2.0-0ubuntu1 )...

It will work again this time.

However, I learned the following knowledge:

1 apt-Get is downloaded to the/var/Cache/archieve directory by default.

2. Use dpkg-I to register for the. Deb file, instead of making, make install
