Comment 1 for bug 268673

Hellow all,
I have solved this problem.
just rename all .DEB files and remove "1%3a", "2%3a", "3%3a", "4%3a" from filename.

STEP BY STEP:
1) First, just go to cache folder with this command :
"cd /var/cache/apt/"

2) Now CHMOD "archives" folder to make permission to rename files inside this folder.
"sudo chmod -R 777 archives/"

3) Now, do this commands one by one in terminal/konsole to rename all .DEB files :
"for FILE in $(find . -type f -name '*1%3a*'); do NEWNAME=$(echo $FILE|sed s/'1%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*2%3a*'); do NEWNAME=$(echo $FILE|sed s/'2%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*3%3a*'); do NEWNAME=$(echo $FILE|sed s/'3%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*4%3a*'); do NEWNAME=$(echo $FILE|sed s/'4%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*5%3a*'); do NEWNAME=$(echo $FILE|sed s/'5%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*6%3a*'); do NEWNAME=$(echo $FILE|sed s/'6%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*7%3a*'); do NEWNAME=$(echo $FILE|sed s/'7%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*8%3a*'); do NEWNAME=$(echo $FILE|sed s/'8%3a'//); mv -v $FILE $NEWNAME; done"

"for FILE in $(find . -type f -name '*9%3a*'); do NEWNAME=$(echo $FILE|sed s/'9%3a'//); mv -v $FILE $NEWNAME; done"

(Help : This command will remove the "1%3a" with "2%3a" "3%3a" "4%3a"... till "9%3a" )

4) DONE...

and after doing this, create iso and see the error would gone.
