Cant add repositories after ubuntu upgrade?

meniscus · 07-06-2007, 05:00 AM

I upgraded from ubuntu dapper to feisty there yesterday and every time i try an add the universe and multiverse repositories i get the following.

Code:

E: Could not get lock /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the list directory

I get a similar error via the command line when i type

Code:

sudo aptitude update

Any suggestions on what i might do to fix this?

Thanks

First make sure you don't have any apt/synaptic/aptitude/etc. running. Then simply remove the 'lock' file and re-try. The file is there to prevent the usage of multiple instances of those apps at the same time; if it's there while the program isn't running, you can safely remove it.

That did it! Thank you.

It gave me these errors..

Code:

W: Duplicate sources.list entry http://archive.ubuntu.com edgy/main Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_edgy_main_binary-i386_Packages)
W: Duplicate sources.list entry http://archive.ubuntu.com edgy/restricted Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_edgy_restricted_binary-i386_Packages)
W: Duplicate sources.list entry http://archive.ubuntu.com edgy/universe Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_edgy_universe_binary-i386_Packages)
W: Duplicate sources.list entry http://archive.ubuntu.com edgy/multiverse Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_edgy_multiverse_binary-i386_Packages)

Should i worry about them?

No, I don't think so. "Duplicate entry" simply means that those lines it showed are written at least two times in the reposity files; apt-get doesn't do anything with identical duplicate lines, so it warns you that there are unneeded lines there (which just take up space from the file).

If you don't want to see the error message all the time, you can simply go trough the reposity files and remove all duplicate lines.

If you want that easily done, you can do it with uniq. It's a tool to remove duplicate lines; command works like

Code:

uniq infile outfile

where uniq reads 'infile' trough, removes duplicate lines and puts the output to 'outfile'. So just feed the reposity files to uniq (one by one, unless you want to script) and copy the output over the input. Probably just as easy is if you open Synaptic, reposity configuration and scroll trough the content, removing duplicate lines if you happen to see any.
