Package gdb is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

Is only available from another source

E: Package 'gdb' has no installation candidate

The online solution is to update the source apt-get update, but there is no better source address at present

Solve

1) install termcap

Wget https://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz

. / configure

Make

Make install

2) install gdb

Wget http://ftp.gnu.org/gnu/gdb/gdb-7.8.tar.xz

Tar-xf gdb-7.8.tar.xz

Cd gdb-7.8/

. / configure

Make

Sudo cp gdb/gdb / usr/local/bin/gdb

Be careful

Gdb encountered an error when installing with source code: no termcap library found, installing termcap
