I try to install old 1.4.2_08 jre, but have error: tail: cannot open `+477' for reading: No such file or directory Checksumming... 1 The download file appears to be corrupted. Please refer to the Troubleshooting section of the Installation Instructions on the download page for more information. Please do not attempt to install this archive file. As I see in rpm.bin the problem is in: if [ -x /usr/bin/sum ] ; then echo "Checksumming..." sum=`/usr/bin/sum $outname` index=1 for s in $sum do case $index in 1) sum1=$s; index=2; ;; 2) sum2=$s; index=3; ;; esac done if expr $sum1 != 26516 || expr $sum2 != 13533 ; then echo "The download file appears to be corrupted. Please refer" echo "to the Troubleshooting section of the Installation" echo "Instructions on the download page for more information." echo "Please do not attempt to install this archive file." exit 1 fi but I dont know what to do? what is that sum file? I need only this version because I have software that suport only that java version I have FC5 and java 1.4.2.13 instaled without eny problems.
